Proof of New Birth
A newborn baby once delivered is given to its parents by the hands of the doctor, a midwife, or a nurse. You would not see this done by only one hand. Similarly, the new birth is not a one-handed event. The two hands of faith and repentance bring the new life to its parents for feeding and care.
We are brought to the new mother, heaven, the new Jerusalem, who is free; (Galatians 4:16) and to the heavenly Father who sired us; and to the milk of His word, whereby we grow. (1 Peter 2:2)
We are never the same after the new birth, but in repentance and faith turn from our former way of life, continuing to pray, read, study, memorize and meditate on the truths of God’s Word. We are continually growing closer to God, being transformed by the renewing of our minds as He, through His Word and Spirit, conforms us to the image of Christ, His Son. (Romans 12:1-2 and 8:29) We desire to know and love Him more; to please Him in all things; we love the things He loves; we serve and worship Him above all things.
Proof of a new birth will be seen as we grow in the grace and knowledge of our Lord Jesus Christ. Physical life does not stop after we are born. We are not left in a crib the rest of our lives. We are fed, and we grow and develop into adulthood. And so, our new birth in Christ will show the signs of the nature and disposition of Christ in us as we grow in our relationship with Him. The love of God, by which He brings regeneration, is the same love that keeps us, and continues to grow in and through us. The love that is spread abroad in our hearts is the love by which we love Him and others. We could not love God and others before this new birth. John speaks plainly in his letters of this love.
Love Begets Love
“Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God.” 1 John 4:7
“We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death. Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.” 1 John 3:14,16
Love takes on a different meaning in our new birth. Love for the things of God displace our love for the world.
“Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him.” 1 John 2:15
Some Christians say that they cannot tell you the day or time of their new birth; but, they know that their life was changed; that as God brought them in faith and repentance to Christ He has kept them by His power to persevere and to be victorious over sin. They have not turned back, but have continued to walk with Him and to grow in their relationship with Him.
“By this we know that we love the children of God, when we love God, and keep his commandments.” 1 John 5:2
The new birth, with the new heart, keeps us to God’s Word for the instructions that He has set forth for His people and His kingdom. Our applying ourselves to know, believe and obey is part of His work in us, for our pattern of life so that we can say, “I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day.” 2 Timothy 1:12
“For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.” Ephesians 2:10
