Uncertainty can make a person feel stuck between fear and faith. Trusting God in that place means giving Him the weight of what you cannot control while still obeying what you already know.
You may not know how everything will unfold, but you can pray, stay truthful, keep your heart soft, and take the next right step. God often leads people a little at a time.
Faith is not always loud. Sometimes it looks like a quiet obedience that refuses to let fear become the final guide.
