The Lord will give you, if you ask, the feelings of the compassion He feels for those in need.
As you pray and serve others, your knowledge that you are a child of God and your feelings about Him will grow.
Our feelings of separation from God will diminish as we become more childlike before Him. That is not easy in a world where the opinions of other human beings can have such an effect on our motives. But it will help us recognize this truth: God is close to us and aware of us and never hides from His faithful children.
It is hard to repent, to admit you are wrong on faith alone before the evidence of a feeling of being forgiven and light comes.
