If you're like me, many things in life discourage you, but none more than yourself. Given the depth of our sin-prone hearts that shouldn't surprise us. Where, then, can we find encouragement to keep going to get optimistically joyful? In God.
"Your Lord is not away somewhere and He never sleeps. He never greets your calls with a busy signal. He is never too tired or too busy to respond. He will never mock your ignorance or weakness, and He does not cruelly throw your failure in your face. He will never threaten that He is at the end of His rope with you. He will not grow weary of your inconsistencies, bored with your ambivalence or irritated when once again you fall short.
His loving face will always be toward you and, because of the cross, you will never see the back of His head. He will meet your moment by moment needs - providing strength from His Spirit, wisdom from His Word, resources from the body of Christ, forgiveness that is your daily need and deliverance from constant temptation. Even the trials He sends your way will supply what you need: the character to live for Him more effectively. These are all the evidences of His commitment to you, that you might be who you are supposed to be and do what He has created you to do."
- Paul Tripp, Broken-Down House, p. 223
