Pray for courage in generating and taking opportunities to speak the gospel.

Even Paul asked for prayer for courage and the confidence that he was speaking the right and best words. Pray that God would give you the boldness, that when presented with an opportunity, you would speak out the truth in Christ and share the gospel, and that he would give you the words.
Pray for the other Christians in the lives of your family and friends.

God almost always uses a succession of people to share the gospel with people before they are saved. You have already prayed that God would put other Christians in their path, pray now for those Christians. That they too would provide an example of Christian living and that they too would speak the gospel.
Pray that God would use any circumstance to do his work in them.

We pray to a God who is sovereign and who sovereignly works his good will. Often he saves people through difficult circumstances, through bringing them to the very end of themselves. Pray, then, that God would arrange circumstances, whether easy or difficult, whatever is required to lead them to salvation.
