1. When we are “called” to do so for God, we respond obediently to God’s will for us, to which He prepares us according to His time, His message, His plan.
2. When we “offer” to do so for God, it is because we have decided to do so out of our own ability, which will still be well received as long as we do it with pure intentions (meaning in an effort to glorify God).
I believe either can be equally effective. Romans 8:28 says, “And we know that in all things God works for the good of those who love him, who have been called according to his purpose.”
From which perspective do you use your talents? Are you called to use art as an expression of faith? Or are you offering to use art as an expression of faith? What has been your experience?
