The more you come to know the Bible - both in reading it extensively and also meditating on it deeply - the more integrated your understanding of all of life will be. And this means that there will be fewer steps between what you are doing at work and sharing your faith in Christ.

The important thing when you are tied down is to continue to model Christ's love. This will ensure that your words, perhaps spoken long ago, will have fresh relevance, or it will help little ones to understand what it means to live the Christian life in days to come. A life well-lived in these circumstances can be hugely useful in evangelism.

Indeed, some secularists are so worried about Christianity, they think Christians are about as dangerous as Muslim terrorists. They get really worried when we don't invest our lives in this-worldly concerns. They look on us as unpredictable free agents. When we reject their relativism and make absolutist spiritual claims, they look at us as nervously as they would a terrorist with a suicide bomb strapped to his back. Of course, Christians are not into coercion in any form. But it is very hard to persuade secularists of that.

I don't see a clerical class in the New Testament to which evangelism has been delegated. Preaching is not the only way to evangelize; it can happen in everyday conversations too. And you don't need a special gift to witness to the Lord in these situations.

We may be sinking in the North Atlantic in the most famous ship disaster of all time, but God can still use us to reach out and save others through our witness.

The truly changed, truly converted, truly Christian heart can say with John Newton, “I am not what I ought to be. I am not what I wish to be. I am not what I hope to be. Yet I can truly say, I am not what I once was. By the grace of God, I am what I am.

God's eternal plan has always been to display his glory not just through individuals but through a corporate body.
