One of the reasons God comforts us is so that we can comfort others.
There are certain things God gives us that we couldn’t possibly give to others. For example, God saves us by His grace, but there’s no way we can save anyone else. Nor can we heal others, give others a future and a hope, or forgive sins. We accept those things and thank God for them knowing they can’t be duplicated.
There are other things God give us that he expects us to give to others. Forgiveness is one of those things. God expects us to forgive others just as He has forgiven us (Matt. 6:14). God loves us, and He expects us to love others (1 John 4:11). God also comforts us, and He expects us to comfort others.
If God has given you a lot of comfort in your life, it means you have done a lot of suffering. Now use your experiences to help relieve the suffering of others.
“I would speak in a way that helps you. I wouldn’t try to take away your grief.” Job 16:5
