Be wise in the way you act toward outsiders; make the most of every opportunity.

Colossians 4:5 New International Version

If for some reason or other that your circle of friends is mostly Christians, it is good to broaden your friendship base.  Build and nurture genuine relationships with your unchurched friends and making the most of every opportunity to bless them and do whatever good you can for them.

The thing that keeps people out of the church is that the way we do church is often designed for churched people, and not unchurched people.  But the good thing is most churched people are acquainted with unchurched people and they are strategically positioned by God in a place of influence. 

The Apostle Paul tells us to act wise and behave in a smart way, especially if we want to influence and impact our friends and neighbours for Christ. Be real and be authentic, and not be afraid to share your struggles and even failures and how you follow God through them. Unchurched people are not looking for perfect Christians but honest ones despite not having everything together all the time.

When unchurched people can see you for who you are and how genuine you are with them, they will feel safe and be more comfortable and more open to hear the gospel for what it is. That is the power of God that brings salvation to everyone who believes (Romans 1:16).

Sharing the good news is more than preaching it, it's about living it. 

This is most helpful because we don't want to turn making friends with unchurched people into a task or a project. That is, our focus is not solely about them becoming followers of Jesus but building a lifelong and trustful relationship with them. Friendship with an agenda is never true friendship. Even if our unchurched friends will not receive Jesus as their personal Saviour, keep caring for them and making ourselves available to them. In doing so, we are trusting God for whatever outcome He deems best.
