“(Charity) rejoiceth not in iniquity, but rejoiceth in the truth” (1 Corinthians 13:6)
Love will not allow us to rejoice in iniquity. Neither will it allow us to rejoice when anyone is reaping the consequences of their iniquity.
“Rejoice not when thine enemy falleth, and let not thine heart be glad when he stumbleth: Lest the LORD see it, and it displease him, and he turn away his wrath from him.” (Proverbs 24:17,18)
There is rejoicing that is evil. (James 4:16) Rejoicing when an enemy falls is evil and displeases God because He takes no pleasure in the death of the wicked. (Ezekiel 33:11) God wants to see His heart in us. He not only wants us to hate what He hates, but He wants us to love what He loves. He hates evil; but He also delights in mercy.
“Who is a God like unto thee, that pardoneth iniquity, and passeth by the transgression of the remnant of his heritage? he retaineth not his anger for ever, because he delighteth in mercy.” (Micah 7:18)
Let go of all that God hates: anger, wrath, bitterness and evil speaking. Hate any hint of maliciousness in your spirit. Wish no one, not even your worst enemy, any harm. Though you are cursed, do not return evil for evil; bless and do not curse. Let what God loves fill your heart. Delight in mercy!
