Distribute God's Word and evangelistic literature promiscuously.
If there ever was a proper use for the word "Promiscuous" we have it. Amen!!
I would recommend people to Ray Comfort's "method" of quickly presenting a gospel and engaging people's consciences.
Living Waters University, Justin - YouTube - and there are heaps of other similar videos. The Law-grace approach cuts all the pleasantries out, and engages the ungodly head on.
But yea, evangelism must flow not just out of
knowledge of the Gospel, but of
intense gratefulness for the mercies Jesus has shown each of us. From this will flow an
irrepressible desire to share with others that love. And gird yourself for suffering. Prepare to lose all your non-christian friends. All of them if God so hardens their heart against the gospel. If you preach the gospel to everyone you come across, they will gnash their teeth at you and want to kill you. They will say:
"Keep your religion to yourself and don't push it down my throat". (that is, if you preach a Puritan gospel)
I've lost many worldly "friends" because I've finally dared to speak up. All that "relationship building" becomes powder puff overnight when you preach the gospel. But I'd rather they hear the gospel, of their sin, God's wrath and the Love of God revealed in the person of Christ - than I be their "friend" while they stumble to the slaughter.
It's not easy!!! Gotta keep praying those Col 4:3 and Eph 6:19 prayers!!!
EDIT: If you want to learn about how to evangelise in a 1 to 1, or a street outreach context, contact the puritanboard member "Josh Williamson" who posted above. He has plenty of experience and advice he can offer. Be blessed!
