Note 5 at Mk. 2:6: God gave us the mental faculties to be able to reason, and in Isaiah 1:18, He enjoined the nation of Israel to come and reason together with Him. Paul reasoned with people using the scriptures (Acts 17:2; 18:4,19; 24:25). So we see that rational thought or logic in itself is not wrong.

However, in Matthew's account of this incident (Mt. 9:4), Jesus called these people's reasoning "evil thoughts." Reasonings become evil when they fail to take God's revealed wisdom (the Word of God--Prov. 2:1-2,5-6) into account. These men would have been correct in their thinking if they would have been dealing with anyone else but Jesus. But the scriptures had shown that the Messiah would take away our sins (Isa. 53:5,10-12), and they should have used God's Word as the basis of their reasoning (Jn. 5:39).

This is where science and psychology today go astray, because they are trying to find the truth and yet they reject the source of all truth (Jn. 14:6; 17:17; Col. 2:3). Anyone who tries to comprehend God's creation without taking God and His revealed wisdom into account is operating in evil reasoning and is a fool (Ps. 10:4; 14:1). "Professing themselves to be wise, they became fools" (Rom. 1:22; 1 Cor. 1:18-21; 2:11-16).
