Read Ephesians 2:1-10
God saved you by his grace when you believed. And you can’t take credit for this; it is a gift from God. Ephesians 2:8 (NLT)
It is essential that we always remember that the difference between the Church and the World is totally due to the grace of God, and not to anything we do on our own. We can’t have fellowship with God or with each other without the grace of God. But God’s grace also allows us to deal with outsiders graciously as well. Our grace-based faith is unique.
