The power of God is manifested through the gospel (Good News) of Jesus Christ to the poor, to the sick, to the person who has an inferiority complex, to the person who feels condemned all the time, to the lonely, to the student, to the homeless, etc...
Remember in God's Kingdom (when you comes in as new creation that's born again), the news is always good, so reject any message that brings condemnation, fear or rejection; such message is not from God. In other words, whatever your circumstances, the gospel is good news because you’re born in the image and likeness of Christ. Genesis 1:26 says; And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
The Holy Spirit through the Apostle Paul says in; Romans 1:16-17(MSG) It’s news I’m most proud to proclaim, this extraordinary Message of God’s powerful plan to rescue everyone who trusts him, starting with Jews and then right on to everyone else! God’s way of putting people right shows up in the acts of faith, confirming what Scripture has said all along: “The person in right standing before God by trusting him really lives.”
So The Gospel (good news) to the poor is that God has supplied all his needs.
And my God will liberally supply (fill to the full) your every need according to His riches in glory in Christ Jesus. (Philippians 4:19 AMP). He did this that He might clearly demonstrate through the ages to come the immeasurable (limitless, surpassing) riches of His free grace (His unmerited favor) in [His] kindness and goodness of heart toward us in Christ Jesus. (Ephesians 2:7 AMP).
The Gospel (good news) to the sick is healing is available to him in Christ Jesus.
But unto you who revere and worshipfully fear My name shall the Sun of Righteousness arise with healing in His wings and His beams, and you shall go forth and gambol like calves [released] from the stall and leap for joy. (Malachi 4:2 AMP). And He went about all Galilee, teaching in their synagogues and preaching the good news (Gospel) of the kingdom, and healing every disease and every weakness and infirmity among the people. (Matthew 4:23 AMP) And Jesus went about all the cities and villages, teaching in their synagogues and proclaiming the good news (the Gospel) of the kingdom and curing all kinds of disease and every weakness and infirmity. (Matthew 9:35 AMP).
And departing, they went about from village to village, preaching the Gospel and restoring the afflicted to health everywhere. (Luke 9:6 AMP). But when the crowds learned of it, [they] followed Him; and He welcomed them and talked to them about the kingdom of God, and healed those who needed restoration to health. (Luke 9:11 AMP).
Gospel (good news) to the person who has an inferiority complex is that there’s deliverance from that complex, and restoration of a sound mind.
For God did not give us a spirit of timidity (of cowardice, of craven and cringing and fawning fear), but [He has given us a spirit] of power and of love and of calm and well-balanced mind and discipline and self-control. Do not blush or be ashamed then, to testify to and for our Lord, nor of me, a prisoner for His sake, but [with me] take your share of the suffering [to which the preaching] of the Gospel [may expose you, and do it] in the power of God. (2 Timothy 1:7-8 AMP).
Gospel (good news) to the person who feels condemned all the time is there’s no condemnation to him any more.
Therefore, [there is] now no condemnation (no adjudging guilty of wrong) for those who are in Christ Jesus, who live [and] walk not after the dictates of the flesh, but after the dictates of the Spirit. 2 For the law of the Spirit of life [which is] in Christ Jesus [the law of our new being] has freed me from the law of sin and of death. (Romans 8:1-2 AMP).
Gospel (good news) to the student is that he’s the head and not the tail.
And the Lord shall make you the head, and not the tail; and you shall be above only, and you shall not be beneath, if you heed the commandments of the Lord your God which I command you this day and are watchful to do them. (Deuteronomy 28:13 AMP).
Gospel (good news) to the homeless is that he has provided a home.
For His divine power has bestowed upon us all things that [are requisite and suited] to life and godliness, through the [full, personal] knowledge of Him Who called us by and to His own glory and excellence (virtue). By means of these He has bestowed on us His precious and exceedingly great promises, so that through them you may escape [by flight] from the moral decay (rottenness and corruption) that is in the world because of covetousness (lust and greed), and become sharers (partakers) of the divine nature. (Peter 1:3-4 AMP).
Gospel (good news) to the lonely is that Someone now lives in him, and has come to be with him forever.
I have been crucified with Christ [in Him I have shared His crucifixion]; it is no longer I who live, but Christ (the Messiah) lives in me; and the life I now live in the body I live by faith in (by adherence to and reliance on and complete trust in) the Son of God, Who loved me and gave Himself up for me. (Galatians 2:20 AMP)
If you [really] love Me, you will keep (obey) My commands. And I will ask the Father, and He will give you another Comforter (Counselor, Helper, Intercessor, Advocate, Strengthener, and Standby), that He may remain with you forever— The Spirit of Truth, Whom the world cannot receive (welcome, take to its heart), because it does not see Him or know and recognize Him. But you know and recognize Him, for He lives with you [constantly] and will be in you. I will not leave you as orphans [comfortless, desolate, bereaved, forlorn, helpless]; I will come [back] to you. (John 14:15-18 AMP).
All this is backed up by deity, so you can go ahead and rejoice all day and all night, for the rest of your life as you’re sure to come out victorious in every situation. For whatever is born of God is victorious over the world; and this is the victory that conquers the world, even our faith. Who is it that is victorious over [that conquers] the world but he who believes that Jesus is the Son of God [who adheres to, trusts in, and relies on that fact]? (1 John 5:4-5 AMP).
For [the Spirit which] you have now received [is] not a spirit of slavery to put you once more in bondage to fear, but you have received the Spirit of adoption [the Spirit producing sonship] in [the bliss of] which we cry, Abba (Father)! Father! The Spirit Himself [thus] testifies together with our own spirit, [assuring us] that we are children of God.
(Romans 8:15-16 AMP).
But even if our Gospel (the glad tidings) also be hidden (obscured and covered up with a veil that hinders the knowledge of God), it is hidden [only] to those who are perishing and obscured [only] to those who are spiritually dying and veiled [only] to those who are lost. For the god of this world has blinded the unbelievers’ minds [that they should not discern the truth], preventing them from seeing the illuminating light of the Gospel of the glory of Christ (the Messiah), Who is the Image and Likeness of God. For what we preach is not ourselves but Jesus Christ as Lord, and ourselves [merely] as your servants (slaves) for Jesus’ sake. For God Who said, Let light shine out of darkness, has shone in our hearts so as [to beam forth] the Light for the illumination of the knowledge of the majesty and glory of God [as it is manifest in the Person and is revealed] in the face of Jesus Christ (the Messiah). However, we possess this precious treasure [the divine Light of the Gospel] in [frail, human] vessels of earth, that the grandeur and exceeding greatness of the power may be shown to be from God and not from ourselves. (2 Corinthians 4:3-7 AMP).
What's more, the new life in Christ is devoid of diseases and infirmities:
Romans 8:11 (AMP) says; And if the Spirit of Him Who raised up Jesus from the dead dwells in you, [then] He Who raised up Christ Jesus from the dead will also restore to life your mortal (short-lived, perishable) bodies through His Spirit Who dwells in you.
No germ, bacterium, virus or disease can thrive in your body successfully because your body has become the temple of the Holy Ghost, the Spirit of God dwells in you. Glory to God.
