Grace (as I understand it) is stated in part by the well known acronym “God’s riches at Christ’s expense.” It is the unmerited favor of God, which is His mercy in action, at work in us. The power of God unto salvation. The sufficiency of God manifested in our weakness, as His power accomplishes it’s purpose, giving His strength to brace us up where we fall short, making us able to stand firm as His servant. Grace is powerful. It’s the power of God at work in us.
