Wants a Message of Help

Dear Sir,
I saw your address in a small Testament, and as you invite anyone to write to you, I thought I would do so. I should be glad if you could write me just a message to help me. I have given my heart to the Lord Jesus, but I do not grow in grace. I pray for strength, but at times I feel so indifferent, my heart feels stony, and not a heart of flesh. I should be so glad and thankful if you could help me. H. D.
