For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them. Ephesians 2:10
God has created us with good works to accomplish. He choose us before the foundations of the world. We are saved by God's grace and it is his grace that sustains us. No one can snatch us out of the Lord's hand. When we believe that our life is insignificant it is a lie from Satan. Every believer has an essential role to play in God's kingdom. The Lord daily is separating His people to Himself.
