​Oh, give thanks to the Lord , for He  is good! For His mercy endures forever.

Psalms 136:1 NKJV

His MERCY endures FOREVER.
If you ever forget this, read Psalm 136. Read the Parable of the Prodigal Son Luke 15:11-32. 
And we are meant to follow in His example. Extend mercy, friends. Forgive that unforgivable thing that was done to you. Be merciful towards those who do not deserve your mercy. Extend love to those who will not love you in return. Offer truth and salvation and wisdom to those who will even refuse it and mock and ridicule you. 

So speak and so do as those who will be judged by the law of liberty. For judgment is without mercy to the one who has shown no mercy. Mercy triumphs over judgment.

James 2:12‭-‬13 NKJV
