I worship God on the basis of my relationship with Him. I recognize Him as “high and lifted up” (Isaiah 6:1) but I also enter into his presence “boldly” (Hebrews 4:16.) Such confident worship is available only to God’s children.
It is only because of my relationship with Him that I am allowed to approach Him at all, except to say “Please forgive me. I am a sinner.” I am his child (Romans 8:16.) This father-son relationship between us gives me access to Him, no matter what my failures or shortcomings might be.
So when I worship Him I recognize that his power, knowledge, majesty and holiness are far beyond my understanding. BUT I also know that his fatherhood provides love, mercy and protection that will never end.
If I knew God only as a stranger I would have to worship Him only in fear and trembling, resembling Isaiah’s “Woe is me” (Isaiah 6:5.) But I know Him as my Father, so my fear and trembling are accompanied with a confident “Abba, Father” (Romans 8:15.)
Nothing can change this relationship. It is secure for all eternity.
