When life or people disappoint us, we have a responsibility to remain stable and continue with God's purpose for our lives.
Consider Psalm 94:12-13. Notice that it does not say that God keeps us calm. It says He gives us power to keep ourselves calm. We are partners with God. His part is to give us ability and our part is to be responsible.
Responsibility means 'to respond to the ability we have.' An irresponsible person wants God to do everything while he does nothing except follow his feelings. But don't let your feelings run the show. Declare out loud right now, "I have attended my last pity party." I can promise you: in the end you will feel much better about yourself if you take responsibility than if you avoid it.
God cares for you, but He won't do your part. He enables you to do it, but let me emphasize that He won't do it for you! I dare you to stand firm, take responsibility and begin working with God to have the blessed life He's planned for you.
Prayer Starter: God, Your Word says that You've given me the ability to remain calm. I receive that today. I won't let my feelings run my life, and I will be responsible and respond the way You want me to.
