"just do it"
Deuteronomy 4 says "Don't add or subtract from the things God is telling you to do...just obey." Just obey. Sometimes that's all there is to it, huh; just obey. We struggle and squirm and try to wiggle out of a circumstance but, the reality is, if we'd just obey, the situation would correct itself.
Where do you need to just obey? Over a decision of employment? In an area of honesty with your spouse? In an area of discipline where your body or health is concerned? Isaiah 42:6 promises us that if we'll just obey, the Lord will "...hold [our] hands and protect [us]."
So, what are you waiting for? As the Nike company has reminded us for so many years...just do it! Just obey and reap the benefits of a life lived in surrender to God.
