We so often do what we want to do, even when it goes against our conscience. This happens most likely when the action we plan to take does not seem to hurt anyone, at least not right away or directly. We feel the guilt, but we sweep it aside and go ahead anyway. Splurging on something expensive but not really needed or beneficial to us spiritually is one example. I consider this a case of overruling God, strictly speaking, a sin. If the number of times we overrule God exceeds the number of times we listen to him, then we'd better make amendment, for God is to be welcomed, not ignored.
