when we stare at some unwelcome task and feel no strength to do it, we can forget that God often gives strength only as we start doing. The Jordan River stopped only as the priests stepped in (Joshua 3:13). The widow’s oil flowed only as she poured (2 Kings 4:1–6). The ten lepers were cleansed only as they walked away from Jesus (Luke 17:11–14). And often, God works his strength within us only as (and not before) we start working (Philippians 2:12–13).” -Scott Hubbard, ‘Maybe Tomorrow’, How to Overcome Procrastination
God gives us strength for an action not when we think about doing it, but when we begin. Sometimes we need to take a short nap (5-15 min, occasionally longer), take a drink of water, move around and/or eat something to help us do our work well but then we must begin.
