I tell you the truth, whoever hears my word and believes him who sent me has eternal life and will not be condemned; he has crossed over from death to life. - John
Every man is born physically, but to know God means to be spiritually born again. To be born again is very important because it is the key to having a relationship with Him. Without a relationship with the Lord, we cannot receive eternal life and go to heaven to be with Him.
When you believe in Jesus as your Lord and Savior, it will come out of your mouth. Paul said we must “confess with our mouth ‘Jesus is Lord’.” In Matthew 10:32-33, Jesus said,
“Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven. But whosoever shall deny me before men, him I will also deny before my Father which is in heaven.” King James Version (KJV)
