Paul wrote in 2 Corinthians 1:22 that Christ SEALED us and gave us the Holy Spirit in our hearts as a deposit. Imagine a fruit bar inside a protective wrapper. Once opened and left exposed, the bar begins to decay. However, if the bar is sealed in a zip-lock bag, the sweet fruit is preserved. Jesus has sealed our soul, preserving us from the rot of sin. 2 Timothy 2:19, Nevertheless the solid foundation of God stands, having this seal: “The Lord knows those that are His.”
