Many Christians refrain from spending quantity time alone in prayer with God the Father due to condemnation, which is often caused by guilt, shame, and regret. The Gospel of Jesus is the remedy. Perhaps we need to sing hymns to ourselves that remind of the effectual work of our Savior. Some of those hold hymns remind us of His triumph over sin and despair.  Others remind of His matchless character and nature.

What can wash away my sin?
Nothing but the blood of Jesus;
What can make me whole again?
Nothing but the blood of Jesus.
Oh! precious is the flow
That makes me white as snow;
No other fount I know,
Nothing but the blood of Jesus.

There is no one like Him; there is no other. If you are weary and wondering about His love for you, read the following words from Charles Spurgeon. He has some encouragement for us from his commentary on Psalm 147:3:

His deep sympathy with mourners is a special mark of his goodness. Few will associate with the despondent, but Jehovah chooses their company, and abides with them till he has healed them by his comforts. He delights to handle and heal broken hearts: he himself lays on the ointment of grace, and the soft bandages of love, and thus binds up the bleeding wounds of those convinced of sin. This is compassion like a God. Well may those praise him to whom he has acted so gracious a part. The Lord is always healing and binding: this is no new work to him, he has done it of old; and it is not a thing of the past of which he is now weary, for he is still healing and still binding, as the original hath it. Come, broken hearts, come to the Physician who never fails to heal: uncover your wounds to him who so tenderly binds them up! (Spurgeon, C. H. (2009).
