Philippians 1:6 KJV
Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ:
One limitation of being a human being is you would not know how an action you take will work out, even with the best intentions. As Christians, we can be confident about the future because not only does God know the future, He is the Future; He is the Beginning and the End after all. You do not need to worry about how the future will turn out if you do your best. The rest is up to God. “Never be afraid to trust an unknown future to a known God” (Corrie ten Boom).
