If you are employed as a welder and your employer wants a perfect bead, you telll them you are not perfect and are not even going to try, but you still expect your full wages at the end of the week. Are you going to get your full wages or the boot?
Through the Grace of God, each of us with a talent. A tree fell on the side of an elderly widow's house crushing over half of her house. A group of men follow the scripture, and repair the house for her. The men neither expect nor will accept any thing in return.
What we see here are the fruits of the spirit. (I'll leave it to you to find out how many.) When we accept Christ, our life changes from that of a self directed worker to a Spirit lead servant. When that change occurs, we are no longer a slave to sin. We are servants of God. We are not looking for eternal security by what we do. We have eternal security by what Christ did.
