The Lord doesn't need you to glorify and praise The Most High; You do.
Calling you to Him isn't an ego trip of- wanting credit where it is due. No.
Calling you to glorify and pray, comes from a compassion for you to bask in the Love, Grace, Forgiveness, Healing, and Ease that comes with realizing the genuine feeling of gratitude and praise!
See, without us, God is still everything. But without the living/ breathing energy of God, we are weak and dying. God calls us to call upon and rely on Him for everything, to involve Him and relate with Him, to invoke His Holy Spirit into every part of our lives, as a loving parent redirects a child in danger.
We are called, for our own sake! The Lord does not have the ego of a human nature, but reminds us that we have the ability to let go of our worldly nature and bring forth His Holiness, So that we may feel Holy, Good, Loved, and Peace.
God's intention is to Love where it is welcomed. But just like rushing water wears down upon boulders , God will do to hardened hearts! Since we were made from His flowing waters, it is our nature to let Him in, or be worn down back into Him from which we came. Glorify the Most High! We are blessed, and when we feel and believe that, we allow the blessings to rush in!
