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.

Humility is not an 'added extra,' one of the lesser Christian virtues. If you don't have humility, you may be lost.

My task as a pastor is to remind people of the need for balance. If someone wants to stress personal union with Christ, I remind them of the need for knowledge as well. If they want to stress knowledge, I tell them about their need to depend on Christ.

Evangelists have absolutely no desire to physically or emotionally coerce anyone. In a sense, we are like doctors: we have a duty to tell you the truth, care for you, argue with you (if that is useful), but we can't compel you to do anything.

We are all called to initiate involvement in each other’s lives... We covenant together to work and pray for unity, to walk together in love, to exercise care and watchfulness over each other, to faithfully admonish and entreat one another as occasion may require, to assemble together, to pray for each other, to rejoice and to bear with each other, and to pray for God’s help in all this.

As a pastor, I have the opportunity every week to share the gospel publicly in a way that most of the members sitting in our church do not. However, that doesn't absolve them of the responsibility for reaching others with the gospel.

God can use even stray, honest comments to bring people to himself.
