In its basic sense, salvation means the saving of a life from harm and/or death. Scripture in the New Testament readings states that salvation is the deliverance from the penalty and power of sin.

For God so loved the world that He gave his one and only son, that whosoever believes in him shall not perish, but have everlasting life.
John 3:16

If you declare with your mouth, 'Jesus is Lord', and believe in your heart that God raised Him from the dead, you will be saved.
Romans 10:9

Simply put, when we give our lives to God, He snatches us from death for eternity! Amen.
