"God calls us to 'be strong' and we mistake that for a call to omnipotence. We confuse strength to endure trials with an ability to walk unfrustrated through life. We convince ourselves that if we were strong we would never fail, never tire, never hurt, never need. We begin to measure strength in terms of ease of progress. When our illusion of omnipotence is shattered we condemn ourselves for being weak..."
It is the kindness and mercy of God that so coordinates events to instruct us in how this thing really works. He has always been aware of my frailty and how regularly I need Him. If I walk blind to that truth, He is glad to open my eyes. It is His delight and His glory for me to need Him, to be aware of my need, to be grateful for His provision.
