You can not learn to rely on God alone by standing safely on the shore under a sunny sky.
You only learn by being thrown in a stormy ocean with no swimming skills, no life vest and no boat nearby to pull you out off the water.
'Cause only then, when you cannot depend on your own skills or material means or people to save you, you truly realize your salvation is through God only.
'Cause He is the true life vest and through Him alone you can truly be rescued.
Only then will you experience a glimpse of Tawheed.
