Joyful are people of integrity who follow the instructions of the Lord. Joyful are those who obey his laws and search for him with all their hearts. (Psalms 119:1-2)
True commitment puts the Lord as top priority (ala Ro 12:1 & first fruits). If you’re convinced that something is from the Lord, then commit to it wholeheartedly. If you’re not convinced of the prior, then you shouldn’t be doing whatever it is in the first place.
