The gospel has done its work in us when we crave God more than we crave everything else in life - more than money, romance, family, health, fame - and when seeing His kingdom advance in the lives of others gives us more joy than anything we could own. When we see Jesus as greater than anything the world can offer, we'll gladly let everything else go to possess Him.
The Gospel Prayer In Christ, there is nothing I can do that would make You love me more, and nothing I have done that makes You love me less. Your presence and approval are all I need for everlasting joy. As You have been to me, so I will be to others. As I pray, I'll measure Your compassion by the cross and Your power by the resurrection.
The amount which you understand the gospel is measured by your ability to be joyful in all circumstances. If you grasp what a treasure the presence and acceptance of God are, then even when life goes really wrong you will have a joy that sustains you, because you’ll recognize the value of what you have in Him. When life punches you in the face, you’ll say, ‘But I still have the love and acceptance of God, a treasure I don’t deserve.’ And the joy you find in that treasure can make you rejoice even when you have a bloody nose. You have a joy that death and depravation cannot touch.
