Great commentary excerpt from William Barclay on 1 John 5:4, "Whatever is born of God overcomes the world..."

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.
