God disciplines us that we might be shaped into the image of Jesus.
There is always something that we are dealing with. There always seems to be something that gets in the way, that discourages us, that drags us down. How do we keep going when we are tired, discouraged, ready to throw in the towel? We are called to remember Jesus who endured it all: painful beatings, betrayal, abandonment, the crown of thorns, the nails that pierced his hands and feet, and the agony of the Cross. He endured it all in order that we might be saved. Encouraged by Him we are told that we too can endure. We can keep going. The promise of the Christian life is not Easy Street but that we are not alone. God is with us. And in the end, despite what things might look like currently, God wins. Part of the Christian life is this thing called discipline. Discipline may be painful, but it is necessary and helpful in shaping us into the people that God would have us to be. So instead of seeing every bad thing as the end of the world, we are to endure knowing that God can use even pain to help shape us into the people that He would have us to be.
