Not Philosophy but Christ

Today I was encouraged by this verse:

(6) As you therefore have recieved Christ Jesus the Lord, so walk in Him, (7) rooted and built up in Him and established in the faith, as you have been taught, abounding in it with thanksgiving. (8) Beware lest anyone cheat you through philosophy and empty deceit, according to the tradition of men, according to the basic principles of the world, and not according to Christ.
Colossians 2:6-8

As a believer, I am not proud to admit that throughout my Christian life, sharing the Gospel with a non-believer has been a scary thing to me. I am certainly not ashamed of my faith in Jesus Christ. My issue was fear of being attacked with atheistic philosophies that I don't have the "head-knowledge" to refute. Come to think of it, I don't even have the "head-knowledge" to prove that what I believe is true, let alone disprove what I know to be false.

Here's the part where I found encouragement in the passage above. Through these verses and prayer, the Holy Spirit reminded me that even though I don't have any logical reasonings or scientific theories that could convince anyone of anything, what I do have is my testimony. I can share about the blessed refinement that God has done in my heart and mind. I can share about the prayers that God has answered and the miracles by which He has revealed His glory and sovereignty to me. I can share about the joy and peace I have found in the midst trials and brokenness. And the only reason that I can share any of this is because of the cross.

And in saying that, the point of sharing the Gospel is not to prove the existence of God (although it wouldn't hurt), but to present salvation from the wrath of Almighty God through Christ Jesus alone, after all simply believing that there is a God is empty without the saving knowledge of Jesus.

(17) For Christ did not send me to baptize, but to preach the gospel, not with wisdom of words, lest the cross of Christ should be made of no effect. (18) For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God.
1 Corinthians 1:17,18
