There is nothing wrong at all with singing songs to God, friend, I certainly won't condemn you for it. If you knew my path, you'd understand more about what I mean. I have been a "worship leader" for most of my life, and I am at a point in my own life where I feel like I'm being challenged to make sure the words I'm speaking are backed up by the way I live my life, so I don't end up speaking/singing empty and meaningless words to God.
If I sing a song of praise to God, I must ask myself, are these words made true by the proof of my actions, are are they proven empty because of my lack of action? My words are worthless without the evidence of my actions in how I live my life. So what is the kind of worship God finds acceptable, then, my words, or my actions?
1 Cor 13:1 If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal.
James 2:18 But someone will say, “You have faith, and I have works.” Show me your faith without your works, and I will show you my faith by my works.
Perhaps it is true that "not many" filled with the Spirit can keep from singing to God. I don't know whether or not this is true. But no one filled with the Spirit can keep from worshiping God by loving others, "For Christ’s love compels us" 2 Cor 5:14.
Mat 25:31-46
“He will reply, ‘Truly I tell you, whatever you did not do for one of the least of these, you did not do for me.’
