His grace is not sufficient if we are obstinate...!

When God assured Paul , "My grace is sufficient for you", we need to clearly define the terms of God's promise. For example, it cannot mean that a believer will always remain in God's perfect will so as to receive that kind of assurance, no matter what he does. Let's remember that the promise was given for a very specific request from Paul and God saw it fit not to answer Paul in the way he wanted. God was declaring that the answer lies in accepting your condition and learning to live with it since I initiated it, in the first place. Surely that phrase cannot be taken to mean you will never end up in distress because God's grace will always keep you from harm or difficulty. My grace is sufficient for you is a promise that God gives us at times when He is working out something very specific in our lives. This is not a general promise for all time and for any season. There are many occasions in our lives that because of our foolhardiness, we end up not receiving the grace of God. Instead mercy pulls us out and we also have a scar to show our wounds. My grace is sufficient for you has to be qualified with a unspoken condition - 'if you are already abiding in me and have yielded yourself fully to me.'
