New birth is a creative act of the Holy Spirit. It is referred to as being born from above. To be born from below is to be born on earth of the flesh; to be born from above is to be born of the Spirit who comes from above. Through new birth, you enter the kingdom of God. Jesus said, "You must be born again"(John 3:7).
New birth is the work of the Holy Spirit, by God's grace through faith in Christ. It is something that God does in you that you cannot do for yourself. You are born again through a supernatural work of the Holy Spirit. It simply cannot be accomplished by human effort. Therefore, you must be born of the Spirit (John 3:8).
New birth is confirmed by confessing Jesus Christ as your Lord (Romans 10:9; 1 Corinthians 12:3). Personal faith in Christ is evidence of your new birth. (John 1:12-13; 1 John 5:1). Your new birth and faith in Christ occur at the same time. Your new birth is evident by truly believing on the Lord Jesus Christ. Believing on the Lord Jesus Christ is trusting or relying upon Him to save and keep you (Acts 16:30-31).
Your first birth was physical and natural. Your new birth is spiritual and supernatural. Your first birth was through the flesh. Your new birth is through the Spirit. Your first birth was in Adam. Your new birth is in Christ, as a new creation (2 Corinthians 5:17).
