These verses enlighten us on the basic principle of salvation. The acknowledgement and confession of the Lordship of Jesus Christ is the God-ordained way to receive salvation. That's how to be born again, and receive the life of God. Many today are still like Nicodemus, who came to Jesus by night and asked, "…How can a man be born again when he's old…?" (John 3:4). Jesus understood his dilemma and replied, "The one who is born of the flesh is flesh, and the one who is born of the Spirit is spirit." It's one thing for people to know they have to be born again, and another thing for them to know how to be born again. The Lord Jesus explained it by saying, "That which is born of the flesh is flesh; and that which is born of the Spirit is spirit" (John 3:6). It's a natural fact that flesh reproduces flesh but Jesus took Nicodemus to a higher level when He said the Spirit, which is the Spirit of God, also reproduces spirits. The Bible describes God as the Father of spirits (Hebrews 12:9), and anyone who is born again is born of the Spirit; his spirit is recreated by the Holy Spirit. So how can one be born of the Spirit? You're born of the Spirit through the Word of the Gospel—the Word of God (1 Peter 1:23). That's what we read in our theme scripture. If you would believe in your heart that Jesus died for you, and that God raised Him from the dead by His Spirit, and you confess with your mouth, His Lordship, you're saved. This Word of salvation, which is thus received into the heart, imparts eternal life. Therefore, with the heart man believes unto righteousness and with the mouth confession is made unto salvation (Romans 10:10).
