We have God’s power inside of each of us, but our bodies are mere jars made of clay.
But this is for a purpose! It is best that way, so that others may see that the power within us is not from ourselves, but from our God! Any greatness and power that we may show has nothing to do with us. We have nothing that was not given to us by God (1 Corinthians 4:7; John 3:27; James 1:17). Therefore, He should be glorified for all that we do.
I have a natural desire to want the glory for the things I do. This verse helps me to remember that I should bring glory to Him and not to myself, for I could never do the things I do without His power.
I am only a jar of clay, a vessel for His use.
