There never has been a time, there never will be a time, when I am strong in my own strength or strong because of my outward circumstances. I can only ever be strong in Christ. And it is particularly when I am weak through self and circumstance that I need to remember this, in order that by God's grace I might experience what it means to be strong in Christ. So when the going is hard, do not be discouraged, do not lose heart, do not give up - believe in Christ.
