The most important thing I have learned in the last year, and I cling to constantly, is that God is who God is 100% of the time. So, He is good 100% of the time, He is just, holy, in control, loving, etc. 100% of the time - and regardless of where I am or what I am going through - He is still all those things all the time.
"I AM" He said, and He is.
"Doubt doesn't have to drive us from faith, but can push us to grapple deeply with the core question of existence. ... Doubt can drive us to seek God." Catherine Claire Larson. So take heart in times of trial and questions and doubt, believe me, He is big enough to answer all of your questions and doubts.
