Becoming born again at the point of repentance and faith in the Lord Jesus Christ (Acts 20:21) is also when one becomes a new creation in Christ (2 Cor. 5:17). At that same time, the newly saved gets a new heart and becomes radically changed by the Holy Spirit. That is significant. Why? Because before one is God’s child, he is a child of the devil (1 John 3:10), a slave to sin (Rom. 6:20-22), and follows the sinful ways of this world (Eph. 2:2). That cold, dead, truth rejecting and unloving heart of stone must go. We need a spiritual heart transplant! Our heart disease is that bad. This is even shown in the Old Testament:
I will give them an undivided heart and put a new spirit in them; I will remove from them their heart of stone and give them a heart of flesh. (Ezek 11:19)
To put it in different words, we need to have our heart circumcised by the Spirit of God to become alive in Christ and get that tender heart of love, which only God can give:
No, a man is a Jew if he is one inwardly; and circumcision is circumcision of the heart, by the Spirit, not by the written code. (Rom 2:29)
That is when God’s love is shed abroad in our hearts (Rom. 5:5) and the kind of love for Christians, which identifies us as a person with spiritual life, is evident to others:
We know that we have passed from death to life, because we love our brothers. Anyone who does not love remains in death. (1 John 3:14)
QUESTION: Have you had the needed heart transplant required for eternal life? If you have, you will know and others will too! If so, are you still walking in love or have you become murderous in heart due to hate (1 John 3:15). NO murderer has eternal life!
