A great word from Pastor J. C. Ryle from his book ‘Holiness’.
Do you ever try to do good to others? If you do, remember to tell them about Christ. Tell the young, tell the poor, tell the aged, tell the ignorant, tell the sick, tell the dying — tell them all about Christ. Tell them of His power — and tell them of His love; tell them of His doings — and tell them of His feelings; tell them what He has done for the chief of sinners; tell them what He is willing to do to the last day of time; tell it them over and over again. Never be tired of speaking of Christ. Say to them broadly and fully, freely and unconditionally, unreservedly and undoubtingly: ‘Come unto Christ, as the penitent thief did; come unto Christ, and you shall be saved.’
