Signs in Creation 41:53
Soon we will make their eyes see our signs, miracles, proofs and warnings, until the way becomes evident and manifest to them.
With the correct establishment of faith from the wisdom which G-d sent down in the Heavenly Books, the signs G-d put in the creation will become apparent to us if we study nature.
Just look to the heavens you will see order and you feel a sense of peace and tranquility. Also for example, look at the beautiful weeping willow tree a tall strong tree, yet it appears to be sad, its spirit seems low.
Our faith must be establish correctly, our conduct has to be upright and ethical and our spirits will rise and have the peace like we see in the heavens.
