Make a habit of turning often to your blessed living Lord and committing the present situation to Him… everything from a possible promotion to a flat tire.
Christ living in you is greater than your feelings, greater than your fears, greater than your timidity, and greater than your tendency to back off from things.
Now you know there’s something this minute that you can do to obey God. Do that, and the decision with which you have been wrestling may well be taken care of in the process.
