A born again Christian became that way through humility; a recognition of their depravity and need for Christ; death to self as Jesus died for us. A deep belief stemming from the heart, not some whimsical profession or one time prayer. This all results in a radically transformed lifestyle with God the Holy Spirit dwelling inside of you.
A great working on God's part, a miracle, but sadly so many would rather cling to their spiritually dead lives headed to total unending destruction in Hell for all of eternity. Life is serious business; a gracious, precious gift from God.
"Good people" don't get to Heaven, only saved ones do. Are you saved from your sins by true faith in Jesus Christ?
