John 3:3-6, and 1 6-18, AMPC
3 Jesus answered him, I assure you, most solemnly I tell you, that unless a person is born again (anew, from above), he cannot ever see (know, be acquainted with, and experience) the kingdom of God.
4 Nicodemus said to Him, How can a man be born when he is old? Can he enter his mother’s womb again and be born?
5 Jesus answered, I assure you, most solemnly I tell you, unless a man is born of water and [even] the Spirit, he cannot [ever] enter the kingdom of God.
6 What is born of [from] the flesh is flesh [of the physical is physical]; and what is born of the Spirit is spirit.
16 For God so greatly loved and dearly prized the world that He [even] gave up His only begotten (unique) Son, so that whoever believes in (trusts in, clings to, relies on) Him shall not perish (come to destruction, be lost) but have eternal (everlasting) life.
17 For God did not send the Son into the world in order to judge (to reject, to condemn, to pass sentence on) the world, but that the world might find salvation and be made safe and sound through Him.
18 He who believes in Him [who clings to, trusts in, relies on Him] is not judged [he who trusts in Him never comes up for judgment; for him there is no rejection, no condemnation—he incurs no damnation]; but he who does not believe (cleave to, rely on, trust in Him) is judged already [he has already been convicted and has already received his sentence] because he has not believed in and trusted in the name of the only begotten Son of God. [He is condemned for refusing to let his trust rest in Christ’s name.]
What is “Covenant Culture?“ It is a spiritual thing. It is living out of one’s spirit (the true, eternal, real you!). It is living in the Covenant of Grace, provided for us by LORD Jesus Christ, when He shed His pure blood for us on the cross over 2000 years ago, to pay the penalty (that we could never pay!) for all we would ever do wrong in our lives. He did this so that we would not have to suffer in any sense, because He loves us. Never did He want us to experience pain nor hardship nor lack of any kind! He came to restore to us what is ours, through the perfect Plan of God. But we must ask Him for it, and know that He is good and wants us to have it.
So Covenant Culture is living in the Original Plan of the LORD, the abundant life (John 10:10). This is the overcoming life, where we have peace and joy in spite of being in this world and experiencing less-than-heavenly circumstances. It is the life where we know that the Word and Spirit of God alone are our strength, and our faith (believing His Word, both in the Bible and as He speaks to our spirits from within us) are our victory!
The verses below will help you understand more.
Romans 12:1-2 (MSG)
[ Place Your Life Before God ] So here’s what I want you to do, God helping you: Take your everyday, ordinary life—your sleeping, eating, going-to-work, and walking-around life—and place it before God as an offering. Embracing what God does for you is the best thing you can do for him. Don’t become so well-adjusted to your culture that you fit into it without even thinking. Instead, fix your attention on God. You’ll be changed from the inside out. Readily recognize what he wants from you, and quickly respond to it. Unlike the culture around you, always dragging you down to its level of immaturity, God brings the best out of you, develops well-formed maturity in you.
Also, Proverbs 18:4, AMPC:
The words of a [discreet and wise] man’s mouth are like deep waters [plenteous and difficult to fathom], and the fountain of skillful and godly Wisdom is like a gushing stream [sparkling, fresh, pure, and life-giving].
Ask the LORD Who is the Spirit of Truth (John 14:15-17, John 15:26-27, I John 4:4-6) to teach you more about Covenant Culture, and how to live in it, for it is your privilege, honor, and right, when you receive Jesus as your Savior and LORD!
