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.
Mark DeverIt's fine to deal with people's doubts and explain why they have good reasons to believe in Christ. But until we tell them the good news of Jesus Christ, we haven't done our job. They need a saviour that God has provided them in Christ. Once they know that, we can do as much apologetics as we need to.
