There is nothing colder than a Christian who does not work for the salvation of others. You cannot use poverty as an excuse; the widow who threw in her two small coins will accuse you (Luke 21:2-4). Peter said, “Silver and gold have I none” (Acts 3:6). Paul was so poor, he often went hungry and lacked even necessary food (Philippians 4:12). And being lower-class by birth is no excuse either. The apostles were obscure men from obscure families. Or are you uneducated? That is no excuse. The apostles were illiterate (Acts 4:13). Are you weak in body? That is no excuse. Timothy was a person who suffered from frequent illnesses (1 Timothy 5:23). Everyone can serve his neighbour if only he is willing to play his part…Don’t tell me, ‘It is impossible for me to influence others.’ If you are a Christian, it is impossible for you not to influence others! Just as the elements that make up your human nature do not contradict each other, so also in this matter – it belongs to the very nature of a Christian that he influences others. So do not offend God. If you say, ‘The sun cannot shine’, you offend Him. If you say, ‘I, a Christian, cannot be of service to others,’ you have offended Him and called Him a liar. It is easier for the sun not to shine than for a Christian not to do so. It is easier for light itself to be darkness than for a Christian not to give light. So don’t tell me it is impossible for you as a Christian to influence others, when it is the opposite which is impossible.
