Man will give you worldly powers, and make you feel on top of all, note this is temporally and could be redrawn at anytime sending you back to the ground floor of life. However, the Lord Almighty, the one and the only rightful ruler of the Universe, blesses everlastingly.


Knowledge is Power, but Power is not Knowledge. Wisdom is the truthful Power that identifies the Knowledge within the man. And only, I repeat 3x. Only the almighty God has the power to bless the man with his Wisdom forever.

To achieve the Lord's blessings, cease not praying daily, asking for his Wisdom, and you'll be blessed abundantly...
