Paul was warning the church in Colossae to look out for deception by way of a good argument. In verse 3, the Scripture says…“All the treasures of wisdom and knowledge are hidden in Him.” A deceptive argument will try to establish their truth apart from the person of Jesus Christ. They will bring up topics as a way to make you doubt the divinity of Jesus Christ, salvation by faith alone in Jesus, the Trinity, and other arguments alike that will try to push you away from the Lord.
Remember, when you are in a debate, stick with what the Bible states. Be careful not to get out of the Scriptures going inside a rabbit hole. An atheist will be a great example of this. They will try to make you go down their rabbit hole that will get you lost in their illogical thinking. They will try to make you prove the existence of God. They do this because their belief is so unrealistic and impossible to prove that they will shift you away from asking them the questions that they know they cannot answer.
How can an atheist prove that “nothing” created the universe? None of them can. Space itself is expanding outwardly. If you would hit the rewind button, it will show you its beginning. Anything that has a beginning, must have someone to begin it. “Nothing” can’t start anything.
Don’t let the atheist take you away from the Scriptures. Use the Scriptures to show them that God created the universe. And that they need to prove to you their illogical reasoning. Which is more logical? God created everything? Or “Nothing” created everything? It is that basic and simple.
