All the money in the world can't buy you a moment of divine peace. All the good works and charitable deeds and religious rituals in the world will never buy you God's peace. You can't earn it or inherit it or ever be worthy of it—but you can have it for free. Divine peace is a gift.
Are you encouraging or discouraging others? If you fail, do you own up to it? Do you quickly admit your failure to the person you promised and refuse to rationalize around it? If you do, you are really rare . . . but a person of genuine integrity.
Genuine success involves doing what the Lord has called you to do, not just occasionally but continually. It has to do with persistence rather than perfection. When this is your definition of success, you can know that the Lord wants you to succeed.
In order to experience the peace of God, we first must have peace with God, which only comes through complete surrender to Christ as our Lord and Savior. Once we are saved, God's peace is available.
Paul embraced suffering. His inability to rid himself of the “thorn” (whatever it was) or avoid difficult circumstances showcased God’s power working in and through him. Paul preached the gospel, but God was doing the work of saving sinners and building churches. It was God who was strong.
