Prayer does not change God,
it changes the one who offers it.
The important thing is to be honest towards God,
until he himself gives the explanation;
which, whether it is the one you want or not,
is always the best.
To pray is a task for the whole soul.
God possesses all good gifts, and his bounty is greater than human understanding can grasp. This is our comfort, because God answers every prayer; for either he gives what he pray for, or something far better.
The earthly minded person thinks and imagines that whenever he prays, the important thing, the thing he must concentrate upon, is that God should hear what he is praying for. And yet in the true, eternal sense it is just the reverse: the true relation in prayer is not when God hears what is prayed for, but when the person praying continues to pray until he is the one who hears, who hears what God is asking for.
