He who believes and is baptized will be saved, but he who does not believe will be condemned. Mark 16:16

Jesus spoke to them and said, “And these signs will follow those who believe. In My name they will cast out demons, they will speak with new tongues, they will take up serpents, and if they drink of anything deadly it will by no means hurt them, they will lay hands on the sick and they will recover. So then, after the Lord had spoken to them, He was received up into heaven and sat down at the right hand of God.”
