Nathaniel Bassey a renowned gospel minister and pastor gave a vital advice to music ministers on when to say no to invitations even if it hurts. See his message below .
“Dear Music Minister, sometimes in ministry you must learn to say NO, respectfully. In an attempt to NOT hurt people, we tend to say yes to everything and to every invitation. Even when the yes is displeasing to God. When in reality the NO is actually walking in truth and in love.
You may be misunderstood, but as long as this is done from a pure heart, God has a way if vindicating you in the end.
