Dean Elliott teaches on Matthew 7:7-12, an oft quoted scripture section for praying for what you want. But, in context, these verses actually convey the tactical approach for reaching people for the kingdom of God. In verses 3-6, we learn that our story is a big tool for investing in people. Specific prayer is your next big tool, found in verses 7-12. And, we see Jesus live out these verses in John 4.
Additional Scripture: Luke 12:31-34
