Singing praise song is not the only worship...
Worship is a profound word and it doesn't only contain singing, praying, raising your hands in the air, feeing the moment...
Worship can be dance, painting, helping oppressed people, meditating, soaking, running, climbing, offering...
Worship is so personal we can't draw a line to it that sets as standard checklist to fill... It's one of the most liberating thing to do, specifically when alone with Him. It's intimate, affectionate, humbling, comforting — basically it is how He is showing His self to us. It's where authentic seeking the presence of God really happens, though God is omnipresent but having to face with Him in our hidden place reveals the special encounter with Him. It is where we find our refuge. It is where most of the time His download of His power to us.
"Why does God need worship? Why we Christians are encouraged to worship?"
"Isn't it funny that a God like him is vain and He want us to worship Him? Why would He do that?"
Worship is not for Him. Worship is for you. For us. For us to be like Him.
Remember "we become what we worship"? We worship God so we can become like Him. He isn't vain or self-glorifying, He is simply lifting us up to the higher grounds of being as His son and daughters.
Be blessed! ❤️
