Christians owe allegiance to God. He is our heavenly Father, and he has every right to claim complete ownership of our lives. We are required to give Him unbiased and unconditional commitment.
The Bible reference
“And Ruth said, Intreat me not to leave thee, or to return from following after thee: for whither thou goest, I will go; and where thou lodgest, I will lodge: thy people shall be my people, and thy God my God: Where thou diest, will I die, and there will I be buried: the LORD do so to me, and more also, if ought but death part thee and me”
(Ruth 1:16-17 KJV)
