In Proverbs 3: 5-6, Solomon says, “Trust in the LORD with all your heart and lean not on your own understanding; in all your ways acknowledge Him, and He will direct your paths.”
What is, ‘with all your heart’? For me it’s no reservations, no forethought, no doubt, no prior planning about what I’m gonna do if it appears He might not take care of me. Sorry, but if He doesn’t do it, it’s not gonna get done. I am just too flaky. Even on the days when I think I’m the smartest person I know (which is less and less often); without God’s TLC I don’t have a prayer. Same as “Love the Lord with all your heart, and all your soul, and all your strength, and all your mind.” Whatever there is in me that I count as me, I’ve got to turn it over to God. That’s trusting with all your heart.
