"But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth." - Jesus (from Acts 1:8)
The above is the LAST THING Jesus said to his followers before his ascension. I mention it this early Monday morning because as of late I've really been thinking about a 'new strategy' or some new and exciting way to reach people with the gospel.
But the answer is so very simple - BE A WITNESS OF JESUS, WITH POWER
If you have not experienced the baptism of the Holy Spirit (see verse 5 in Acts chapter 1), you don't have the goods (power) you need to witness to anyone about Jesus. Look at how Jesus witnessed to people that he was truly the Son of God - in human flesh - POWER! Look at how the Apostles did it throughout the book of Acts - POWER!
Without a demonstration of POWER - The best you can do it have a debate.
Have you ever debated someone about the gospel? About Jesus? About the realness and reality of God? I have.
Now let me say: sometimes chatting, conversing, and dialogue can be a really positive thing - especially when the talk leads to an encounter with God.
But to debate people in order to convince and change their mind about Jesus... it's just NOT what God calls us to do.
I have learned that as easy as someone can be convinced into something - they can often be convinced out of it. Therefore all your hard work may be in vain if you have spent hours in debate with someone over the claims of Christ and the Bible, and have convinced them intellectually, only to have them be 'intellectualized' into another decision later.
Sidenote: if the Holy Spirit leads you to talk with someone for hours on end - DO IT. There is nothing wrong and everything right with conversing with people and answering tough questions about God, the Bible, the cross of Christ, the gospel, etc. The Apostle Paul conversed, taught, rebuked, exhorted, and preached for hours on end, often. Follow the Holy Spirit's lead 100%!
The issue comes when in our own strength and by our own means and mind we enter into fruitless and frustrating debate. You know what I mean if you have tried to win people to Christ!
Preaching the gospel is meant to be a display of power - witnessing to the reality of Jesus Christ, his cross, and his claims. It's a demonstration of the POWER in the name of Jesus!
It's not really up for debate.
