Greg Ogden challenges us to be praying for those people in our network of relationships that do not know Christ. I recommend that you keep a prayer list, and you come back to it on a regular basis.
Think of those people in your family, your work associates, your neighborhood, who are moving in a direction apart from Christ, but you might be that connecting link to pray for them and be the one who is sharing the Good News of the Gospel.
So make that as a part, even of your covenant. Keep track of those that you have a heart for, and and ask God to open the doors to be able to share the Gospel.
