Then how do YOU know?
Romans 8: 16 The Spirit himself testifies with our spirit that we are God’s children. 17 Now if we are children, then we are heirs—heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in his glory.
Hebrews 10:15 The Holy Spirit also testifies to us about this. First he says: 16 “This is the covenant I will make with them after that time, says the Lord. I will put my laws in their hearts, and I will write them on their minds.”
Christ taught us how to know the saved (by their fruit.).... how do you know someone is a Catholic??
