Reflecting on Ephesians 1:3-6, Bob Kauflin had this to say:
God chose us before the foundation of the world because he loved us. But why did he choose us? Not so that we might endlessly reflect upon ourselves, but for the "praise of his glorious grace." When we worship God, we join an activity that began in eternity and will continue forever - the triune God valuing his beauty and worthy above everything else(From Worship Matters page 176.)
When we worship God, we are joining in something that began in God's mind before time began and is going to continue on forever. When we worship Jesus Christ, we are tapping into eternity! That may change my attitude every time I offer my meager worship to God.
