Acting with faith in God is easiest if the thing you feel God calling you to do looks logical and good and pleasurable and is intrinsically so when you do it. It is harder when the thing you are called to do looks hard, but as you struggle through it you find intrinsic goodness in it. It is hardest when it looks hard and it is painful to go through and you feel exhausted and drained and beaten for as long as you do it.
Singing well in a really good choir or acting in a fun church skit might be an example of the first. Teaching a class of students who you find challenging or raising rambunctious children may be an example of the second. Gethsemane and Golgatha are the ultimate examples of the third.
Jesus life and the life of his early apostles contain examples of all three kinds of faith experiences, including the one that teaches us that sometimes living by faith involves experiencing something that reminds us of Gethsemane or Golgatha.
Thanks to D. for his post who reminded me of this.
