Choose love instead.

So, is it worth it to hold a grudge against someone with whom you disagree? Um, no. Not even close. Not if you believe the Word of God, that is:

Ephesians 4:1

Be completely humble and gentle; be patient, bearing with one another in love. Make every effort to keep the unity of the Spirit through the bond of peace.

Philippians 4:2-3

I plead with Euodia and I plead with Syntyche to be of the same mind in the Lord. Yes, and I ask you, my true companion, help these women since they have contended at my side in the cause of the gospel, along with Clement and the rest of my co-workers, whose names are in the book of life.

1 Peter 4:8 Amplified Bible (AMP)

Above all, have fervent and unfailing love for one another, because love covers a multitude of sins [it overlooks unkindness and unselfishly seeks the best for others].

Paul called love “the most excellent way” (1 Cor. 12:31). It's the top choice for anger over wrongs done to you or your loved ones. And though it may feel difficult for us to pull off, God expects us to do it. Of course, if you call on Him for help in getting there, He will walk you to it and through it. Don't hesitate to ask for His help and guidance.
