“Ask yourself, 'If I were sure that I loved God, what would I do?' When you have found the answer, go and do it.
On the whole, God's love for us is a much safer subject to think about than our love for Him. Nobody can always have devout feelings: and even if we could, feelings are not what God principally cares about.
Christian Love, either towards God or towards man, is an affair of the will. If we are trying to do His will we are obeying the commandment, 'Thou shalt love the Lord thy God.' He will give us feelings of love if He pleases.”
