Going to a Church Building, Saying you are a Christian and Even doing Good Deeds is not Proof you are Saved! Only Trusting in Christ and desiring to be Changed by Him will gain you Salvation

Matthew 7:21-23 "21 “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven.
22 On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’
23 And then will I declare to them, ‘I never knew you; depart from me, you workers of lawlessness.’"
Notice God says: "I NEVER knew you."
