We can't know at any given time how God will bless our faithful witness. So the apparent numerical growth of the church is never a good guide to how faithful we have been in evangelism.

We are called to love others. We share the gospel because we love people. And we don't share the gospel because we don't love people. Instead, we wrongly fear them. We don't want to cause awkwardness. We want their respect, and after all, we figure, if we try to share the gospel with them, we'll look foolish! And so we are quiet. We protect our pride at the cost of their souls. In the name of not wanting to look weird, we are content to be complicit in their being lost.

We should want to evangelize because of the joy that God puts in our hearts. Ultimately, that's the best reason for sharing our faith.

If you think that the gospel is all about what we can do, that the practice of it is optional, and that conversion is simply something that anyone can choose at any time, then I'm concerned that you'll think of evangelism as nothing more than a sales job where the prospect is to be won over to sign on the dotted line by praying a prayer, followed by an assurance that he is the proud owner of salvation.

I think many people in the church are probably concerned that they can't answer all the questions that might come up. I am sure this affects people by playing on their doubts - especially if they have their own questions that they are wrestling with.

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.

If you need wisdom and guidance, then pray to the Lord to guide you.
