There are times when I have not knowingly over committed that I find I am. Usually, this happens when my margin is low. When some unforeseen event happens that drives those aforementioned resources negative. I find myself struggling with Psalm 15:4 and Matthew 5:33 – 37 when that happens.
Those two passages conspire to convince me that if I tell someone I will do something. I had better well do it. It seems to me that more often than not it is these types of circumstances that force me to trust God. To rely on His unlimited resources rather than my sorely inadequate stash.
