There are times when the sheep we’re called to shepherd hurt us.  This statement by Spurgeon spoke to me.

“When others behave badly to us, it should only stir us up the more heartily to give thanks unto the Lord, because He is good; and when we ourselves are conscious that we are far from being good, we should only the more reverently bless Him that He is good.” (quoted from Attributes of God, A. W. Pink, eBook Loc 1116)

“Give thanks to the Lord, for he is good; his love endures forever.” (Psalm 118:1 — and five other times in the Bible)
