Giving Grace

On Sunday Adam was talking about the purpose of grace and how grace frees us (Rom 6: 11-14). In a related thought I was reading yesterday in Ephesians 4:29 about how our talk can "give grace".

Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear. [ESV]

Watch the way you talk. Let nothing foul or dirty come out of your mouth. Say only what helps, each word a gift. [The Message]

I was noticing the contrasts in this verse:

corrupting vs. building up; fitting
foul or dirty vs. helps
