I can do all things through Christ which strengtheneth me.
I see two misunderstandings with this passage. First, people think because they are saved, they have the power to do all things. But this passage really says that everything I do, I can do it through Christ – and that ought to be the goal of every saved person. Second, people believe that the Lord Jesus Christ goes around willy nilly giving them strength. But this passage really tells us that what gives us strength is doing things through Christ. To illustrate, a bodybuilder gets stronger because he exercises his body. A Christian gets stronger because he or she exercises his or her spirit. Your spirit will never get stronger if it is never exercised – if you never do things through Christ.
