By the Holy Spirit to our Spirit, we understand heavenly things, for we have been born again, born of the Spirit and have been regenerated, washed with the washing of the Spirit. (Titus 3:1-11)
Jesus explained that is how we understand, see and enter the kingdom
“Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God. John 3:3 …Verily, verily, I say unto thee, Except a man be born of water and the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. John 3:5-6
“One who believes in the Son has eternal life, but one who disobeys§ the Son won’t see life, but the wrath of God remains on him.” John 3:36 (Jn 3:1-36)
Jesus gave the Samaritan woman at the well more insight.
“You Samaritans worship what you do not know; we worship what we do know, because salvation is from the Jews. But a time is coming, and even now has arrived, when the true worshipers will worship the Father in spirit and truth; for such people the Father seeks to be His worshipers. God is spirit, and those who worship Him must worship in spirit and truth.” The woman *said to Him, “I know that Messiah is coming (He who is called Christ); when that One comes, He will declare all things to us.” Jesus *said to her, “I am He, the One speaking to you.” John 4:22-25 NASB
We understand and applying spiritual things beyond human comprehension.
9 But as it is written,“Things which an eye didn’t see, and an ear didn’t hear, which didn’t enter into the heart of man, these God has prepared for those who love him.”10 But to us, God revealed them through the Spirit. For the Spirit searches all things, yes, the deep things of God. 11 For who among men knows the things of a man except the spirit of the man which is in him? Even so, no one knows the things of God except God’s Spirit. 12 But we received not the spirit of the world, but the Spirit which is from God, that we might know the things that were freely given to us by God. 13 We also speak these things, not in words which man’s wisdom teaches but which the Holy Spirit teaches, comparing spiritual things with spiritual things. 14 Now the natural man doesn’t receive the things of God’s Spirit, for they are foolishness to him; and he can’t know them, because they are spiritually discerned. 15 But he who is spiritual discerns all things, and he himself is to be judged by no one. 16 “For who has known the mind of the Lord that he should instruct him?” But we have Messiah’s mind. 1 Corinthians 2:9-16
The Spirit himself testifies with our spirit.
We understand heavenly things with our spirit and the kingdom of heaven is in the Spirit.
8 Those who are in the flesh can’t please God. 9 But you are not in the flesh but in the Spirit, if it is so that the Spirit of God dwells in you. But if any man doesn’t have the Spirit of Messiah, he is not his. 10 If Messiah is in you, the body is dead because of sin, but the spirit is alive because of righteousness. 11 But if the Spirit of him who raised up Yeshua from the dead dwells in you, he who raised up Messiah Yeshua from the dead will also give life to your mortal bodies through his Spirit who dwells in you. Romans 8:8-11
“16 The Spirit himself testifies with our spirit that we are children of God; 17 and if children, then heirs—heirs of God and joint heirs with Messiah, if indeed we suffer with him, that we may also be glorified with him.” Romans 8:8-17
“The grace of our Lord Yeshua the Messiah be with your spirit, brothers [and sisters]. Amen. Galatians 6:18
“May the God of peace himself sanctify you completely. May your whole spirit, soul, and body be preserved blameless at the coming of our Lord Yeshua the Messiah. 1 Thessalonians 5:23
“The Lord Yeshua the Messiah be with your spirit. Grace be with you. Amen. 2 Timothy 4:22
“The grace of our Lord Yeshua the Messiah be with your spirit. Amen. Philemon 1:25
Then don’t let your good be slandered, for God’s Kingdom is not eating and drinking, but righteousness, peace, and joy in the Holy Spirit. Romans 14:16-17
We are new beings fit for the kingdom of God.
“Therefore if anyone is in Messiah, he is a new creation. The old things have passed away. Behold, all things have become new. But all things are of God, who reconciled us to himself through Yeshua the Messiah, and gave to us the ministry of reconciliation; namely, that God was in Messiah reconciling the world to himself, not reckoning to them their trespasses, and having committed to us the word of reconciliation.” 2 Corinthians 5:17-19
What God has made us.
“9 But you are a chosen race, a royal priesthood, a holy nation, a people for God’s own possession, that you may proclaim the excellence of him who called you out of darkness into his marvelous light. 10 In the past, you were not a people, but now are God’s people, who had not obtained mercy, but now have obtained mercy. 11 Beloved, I beg you as foreigners and pilgrims to abstain from fleshly lusts which war against the soul, 12 having good behavior among the nations, so in that of which they speak against you as evildoers, they may see your good works and glorify God in the day of visitation. 1 Peter 2:9-12
