1 Peter 4:7-11

But the end of all things is at hand: be ye therefore sober, and watch unto prayer. And above all things have fervent charity among yourselves: for charity shall cover the multitude of sins. Use hospitality one to another without grudging. As every man hath received the gift, even so minister the same one to another, as good stewards of the manifold grace of God. If any man speak, let him speak as the oracles of God; if any man minister, let him do it as of the ability which God giveth: that God in all things may be glorified through Jesus Christ, to whom be praise and dominion for ever and ever. Amen.

We never know when the end might come, so we must act accordingly all the time. This means that we must have the love of Christ in us and we must give it out through our actions. Only the love of Christ will save us and will allow us to make it through this life. We must serve God by loving all of mankind.
