18 And do not get drunk with wine, for that is debauchery, but be filled with the Spirit, 19 addressing one another in psalms and hymns and spiritual songs, singing and making melody to the Lord with your heart, 20 giving thanks always and for everything to God the Father in the name of our Lord Jesus Christ - Eph 5:18–20 (ESV)
One of the least utilized practices that I know of is the practice of singing the song of our heart to God. There is a song in the heart of everyone who has had an encounter with God. It is the testimony of Jesus in our life. Who He is and what He has done for us. I love singing all the great worship and praise songs that are out there but I find that very few of them represent what I really want to say to God in the different seasons of life.
Worship isn't something we do, it is who we are; we are worshippers (Jn 4:23). Our spirit longs to worship God, it is as natural for our spirit to worship as it is for our bodies to breathe air. Paul, in the passage above, directly links this kind of singing to being filled with the Spirit! If you want a how-to be filled with the Spirit, this list is a good start!
I have found personally that the deepest and most intimate times of worship have been in times where I stopped singing the words of the song and began to declare who God is to me and start praising Him in my own words.
You may be thinking, that is just too awkward... you are right! It is awkward! For a while that is... This is a spiritual muscle that needs to be worked out. Try it out in the shower or put on a good praise song that can fill the silence, or as I do, play your instrument of choice! Just be yourself and sing to God the song of love and gratitude that your heart is longing to sing!
Tip: Something that still helps me out at times when I don't know what to sing is to find a Psalm or a praise song that does express what you want to say and use it as an onramp!
Have you done this type of singing before? How has it enriched your relationship with God? Please share your story/thoughts!
