"In our daily experience, we have all sorts of spiritual ups and downs - sin, failure, discouragement - all of which tend to make us question God’s love. That is because we keep thinking that God’s love is somehow conditional. We are afraid to believe His love is based entirely upon the finished work of Christ for us. Deep down in our souls we must get hold of the wonderful truth that our spiritual failures do not affect God’s love for us one iota - that His love for us does not fluctuate according to our experience."
Jerry Bridges, The Practice of Godliness.
