Actually, having a few questions of your own shouldn't prevent you from sharing the gospel with others. You can explain to them that while you still have a few unresolved questions yourself, you don't have enough faith to not believe.

Our fears lie to us about how important they are.

There is simply so much reason to believe the good news of Jesus Christ in history, in Scripture, as well as in our own experience that it would take a leap of faith not to believe in the gospel.

I love Iain Murray's definition of worldliness: towards the end of Evangelicalism Divided, he says that worldliness consists of loving idols and being at war with God. I think that's true in the lives of too many professing Christians today.

We live in a time when people are increasingly skittish about evangelism - Christians and non-Christians alike. People are suspicious of evangelism, and misunderstand it, which contributes to our reluctance to share the gospel. When you add our fear of others' reactions as well as our natural laziness to the equation, it's not hard to see why we make such little progress in sharing our faith.

I assume that normally the Lord will be bringing people to himself through the instrumentality of the preached word. However, we have to be very careful that we don't assume that if we are 'X' faithful in evangelism, then we will see 'Y' results right now. It doesn't work like that.

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.
