That if you confess with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved. Romans 10:9-10 (NIV)
This is a promise from God. Our sins are behind us when we confess to our Lord. Our mistakes are forgiven and forgotten when we turn to God. We are saved and there is nothing that can separate us from our Lord.
We don’t need to prove ourselves by doing great works. Great works are meaningless if they don’t first come from God.
We don’t need to redeem ourselves by paying off all we owe to God. That debt was already paid by Christ Jesus when he died on the cross.
We don’t need to force our way into favour with God. He already loves us.
All we need to do is trust him.
When we do this, we become richly blessed. We become God’s children. We become heirs to his Kingdom. We become saved.
