We are blessed to know a God who knows our heart and blesses us with unmerited favor.
We serve a God who has subjected Himself to our weakness and sin.
We love a God who by grace love us infinitely more.
Remember that when you are exhausted with the fight. Remember When you are failing, When you are discouraged, when you are ashamed, when you lack confidence or courage or conviction…
He sees your heart. He has felt the pain of rejection and even hatred to the point of death. He knows your weakness. Your thoughts and struggles and exhaustion are not unfamiliar to Him. 
I love the image of being able to come before God boldly regardless of the temperature of our heart … That he knows us intimately and only waits for us to approach and ask for help. It seems so beautifully simple…help in time of need… But there it is…
“For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who in every respect has been tested as we are, yet without sin. Let us therefore approach the throne of grace with boldness, so that we may receive mercy and find grace to help in time of need” – Hebrews 4:15-16
