(i) We have a defence to resist the infections of the world. On all sides there is the pressure of worldly standards and motives; on all sides the fascinations of the wrong things. From within and without come the temptations which are part of the human situation in a world and a society not interested in and sometimes hostile to God. But once we are aware of the presence of God in Jesus Christ ever with us, we have a strong prophylactic against the infections of the world. It is a fact of experience that goodness is easier in the company of good people; and if we believe in the incarnation, we have the continual presence of God in Jesus Christ.
(ii) We have a strength to endure the attacks of the world. The human situation is full of things which seek to take our faith away. There are the sorrows and the perplexities of life; there are the disappointments and the frustrations of life; there are for most of us the failures and discouragements of life. But if we believe in the incarnation, we believe in a God who himself went through all this, even to the Cross and who can, therefore, help others who are going through it.
(iii) We have the indestructible hope of final victory. The world did its worst to Jesus. It hounded him and slandered him. It branded him heretic and friend of sinners. It judged him and crucified him and buried him. It did everything humanly possible to eliminate him—and it failed. After the Cross came the Resurrection; after the shame came the glory. That is the Jesus who is with us, one who saw life at its grimmest, to whom life did its worst, who died, who conquered death, and who offers us a share in that victory which was his. If we believe that Jesus is the Son of God, we have with us always Christ the Victor to make us victorious.
I came across the following prayer: "Dear Lord So far today, I've done all right. I haven't gossiped; I haven't lost my temper; I haven't been greedy, grumpy, nasty, selfish, or overindulgent. I'm very thankful. But in a few moments, Lord, I'm going to get out of bed. And from then on, I'm going to need a lot of help."
