This is the last night that Christ instructed his disciples, the apostles-to-be before his death on Calvary’s cross. And he is particularly focussing attention on things that they vitally need to understand and which they do not understand.
This speaks to us too. We must believe; we must have faith. Yes, we have believed, let us say, we have trusted in Christ. We have believed that he has suffered and died for us. We have repented of our sins, we have come to him. But it is the first thing that we need to learn as we go on in the Christian life, even if we are veterans, the exercise of faith. What happens in life? There are problems, upsets, disturbances, sometimes doubts, sometimes great causes of grief and disappointments, and we begin to turn these things over in our minds. We may or may not go to pieces momentarily. We may have self-pity or recriminations, and we fail to exercise faith. In the providential plan of God, he knows my circumstances. He knows what is happening to me. I believe in his promises and his goodness. I will trust him. I will not let these doubts and fears and sorrows go round and round in my mind, rule me and pull me down. Stop the troubled motions of your heart. ‘Let not your heart be troubled’ anymore. ‘Ye believe in God, believe also in me.’
