The purpose of God is the will and the plans of God that he has for us, and he works all things, including the things we face in life, according to his purposes. Having faith in him and his plans, even when the pain is overwhelming, is one of the keys to living the abundant life that he has for us. Your pain serves a purpose, even when you don't understand it. And because he is an intentional God and all-knowing, it is the reason we are Pained on Purpose. He is with us when we are going through these pains, helping us and pulling us through so that we can testify of his goodness that he may be glorified, and somebody else can be made free and whole by his Spirit. Pain doesn't have to be the end of your story, but it can be the beginning of what God intended to be a perfect end.
