Bridges are indigenous (naturally occurring) means into the community, which can open up opportunities to share the gospel. Almost anything can be used as a starting point for discussion so that the truth about Jesus Christ can be presented.
And Paul stood in the midst of the Areopagus and said, "Men of Athens, I observe that you are very religious in all respects. For while I was passing through and examining the objects of your worship, I also found an altar with this inscription, 'TO AN UNKNOWN GOD.' What therefore you worship in ignorance, this I proclaim to you." Acts 17:22-23
Pray that the natural bridges into the culture can be used to further the Kingdom of God.
