3:3 What does Jesus mean here that one must be born again to see the kingdom of God?

Being born again means literally being born from above. It expresses the changes wrought in the life of a repentant sinner by the Holy Spirit after being converted to Christ. It means the sinner has died unto sin and has been born anew from above unto righteousness. How this happens is that when the gospel is preached the Holy Spirit awakens in the heart of those open to receiving the gospel, a consciousness of guilt and the need for forgiveness (CP Ac 2:37-38).

As they hear the gospel sinners are made aware by the Holy Spirit of God's standard of righteousness in Christ, and they turn to Christ for salvation (CP Jn 6:44-45; Jn 16:7-11; Ro 1:16-17; 2Cor 4:6).

Being born again is not limited to the initial act of renewal when we are first converted to Christ, but is a continuous work of the Holy Spirit renewing and transforming our lives as we surrender ourselves to the lordship of Christ and the authority of His word throughout the entirety of our Christian walk. This is one of the fundamental doctrines of the Christian faith: the Doctrine of Regeneration, or the New Birth.

Once we have committed our way to God we are no longer to be conformed to a world system that is without God, but transformed by a renewed mind committed to the ideals of the kingdom of God (CP Ro 12:1-2; Eph 4:17-32).

Prove in Ro 12:2 means to test, to prove by practice in everyday life that God's will for us is good and acceptable and perfect. Our minds must be conformed to God's way of thinking. Our plans, goals, and ambitions must be determined by heavenly and eternal truths, not by this evil, temporal, and transient age (CP Ro 6:6, 12-13; 7:5; 8:15-17; 13:14; Ga 5:16-25; 6:7-9).

Being born again involves a complete transformation of our moral nature - a complete change of heart that expresses the change from the person we were, to the person we become in Christ (CP Eph 2:1-13; Col 3:1-17). If we have made the way of Christ our way of life it will very plainly show (CP 2Cor 5:17; Ga 6:15).

To sum up, seeing the kingdom of God is actually perceiving it and its realities through the salvation that can only be obtained through abiding in Christ and having His word abide in us (CP Ac 4:10-12).

Our membership in God's family remains conditional on our love for Christ demonstrated by a life of sincere obedience to His word (CP Jn 14:15, 21-23; 1Jn 2:3-6; 3:6).

Just as we can be born again unto everlasting life by the Spirit of God, we can also extinguish that life by ungodly choices and ungodly living (CP Ro 6:1-23; 8:12-14; 2Ti 2:11-12). See also comments on Jn 1:12-13. 3:5, Tit 3:5 and He 10:22, and author's studies
