Strength

It is possible to reach a state in which you bring your mind under my guidance without conscious effort, but this implies a willingness that you have not developed as yet.

The Holy Spirit cannot ask more than you are willing to do.
The strength to do comes from your undivided decision.

There is no strain in doing God's Will as soon as you recognize that it is also your own.

The lesson here is quite simple, but particularly apt to be overlooked. 
I will therefore repeat it, urging you to listen.

Only your mind can produce fear. It does so whenever it is conflicted in what it wants, producing inevitable strain because wanting and doing are discordant.

This can be corrected only by accepting a unified goal.
