God knows the details. He knows the big picture. He’s the only one with all of the information. Trust Him to make decisions for your life, to guide your path, to arrange your circumstances. He’s the only one who can with wisdom and with a loving heart.
God has the wisdom you need. He has the wisdom you want. Let Him guide you. The world’s “theories” aren’t based on God’s word. His word won’t fail. The world’s ideas may have flashes of truth and an appearance of effectiveness, but they will not produce disciples.
