It is wonderful to be a born-again believer in Jesus Christ because we receive the Holy Spirit and God's divine nature in us. We are new creations in Christ. The old sin nature of our spirit is replaced with a new created spirit in the same image, likeness, and nature of God. We find a joy and peace that surpasses all knowledge and understanding.
The love of God fills our hearts, and for the first time in our lives, we experience what it is to be loved by Almighty God, whom we now call our Father. This is not a religion. This is a RELATIONSHIP! The new birth of our spirit sets us free from sin and spiritual death. So how does this happen, and what did Jesus say about it?
Jesus met with a Pharisee named Nicodemus, a ruler of the Jews. He commented that he knew Jesus had to have come from God to do the signs Jesus was doing. The conversation went directly to man's need for repentance and being born again. Nicodemus did not understand this, but Jesus lovingly walked him through it, and now we will too.
John 3:3. Jesus answered and said to him, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.”
Jesus makes it very clear that we must be born again, or a person will not see the kingdom of God. He also tells us that our spirit is born again, not our flesh.
