Our worship is an indication of our understanding of God. A true understanding of God will naturally induce pure awe of who He is. How can we keep silent and remain unmoved when we know God as the mighty Creator who made all things? How can we fold our hands when we understand that He did not withold anything from us but forsook everything including His own life to ransom our wretched lives. How can we remain unmoved and stand afar when we are understand the truth that God is total virtue, purest light, the embodiment of love and there is no evil vein in all of His being and He completely loves you.
Our souls are created to be drawn by beauty. So if worship of God no longer stirs you, it's because you do not see Him as beautiful as He is. He has not changed. sadly we have grown dim in our sight. We are wearing the wrong lenses and have mistaken the beauty of created engineering and sophisticated devices as the real thing when it is just a passing fad.
Take an honest measure of your worship temperature. David sings ' as the deer pants for the waters, so my soul pants after you'. True knowledge of God leads to lavish worship.
