Worship is part of man’s obligation to God; in fact it is also his highest privilege, but it must be done in a context of love for men.
” We love because he first loved us. If anyone says, I love God yet hates his brother, he is a liar. For anyone who does not love his brother, whom he has seen, cannot love God, whom he has not seen. And he has given us this command: whoever loves God must also love his brother.”(1John 4:19-21)
A man must examine his heart for the weed of hatred, and straighten out his relations with other men before his worship will be acceptable to God.
