We must live deeply ourselves if we would be able to bless others. We must resist sin, even unto blood, if we would teach others how to be victorious in temptation. We must bear trials and endure sorrows with patience, with submission, and with faith, so as to be victorious, if we would become comforters and helpers of others in theirs. You must learn before you can teach, and the learning costs. At no small price can we become true helpers of others in this world. That which has cost us nothing in the getting will not be any great blessing to any other person in the giving, it is only when we lose our life, sacrifice it to God, that we become deeply and truly useful.
