He that believeth and is baptized shall be saved; but he that believeth not shall be damned. Mark 16:16 KJV
The eternal torment of hell (yes, it’s a real place) awaits those unwilling to believe. Eternal righteousness, peace, and joy awaits those who believe and yield their lives to Jesus the Christ of God.
But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. Romans 10:8-10 KJV
