Bro. Koshy Mathew expounds a simple prayer by the psalmist: Search me, O God, and know my heart: try me, and know my thoughts: And see if there be any wicked way in me, and lead me in the way everlasting. He explains the perspective/understanding of the Psalmist, how he accepts the fact of God being Omniscience, Omnipresent, Omnipotent. When this understanding increased, He understood God his Holy and hates wickedness. When this knowledge of God increases he prays this prayer so that He could help him to search his heart.The Lord is an Omniscience, Omnipresent, Omnipotent and also Holy. So we need to cleanse ourselves so that He could use us. If it’s not clean God won’t bless us. We must be gripped by the Holiness of God, if so we could also turn the world upside-down. The Bible says that the heart is deceitful above all and desperately wicked. Are your hearts clean? Bro Koshy then explains this verse in a very concise way.
