But be doers of the Word [obey the message], and not merely listeners to it, betraying yourselves [into deception by reasoning contrary to the Truth].
Hearing what God’s Word says about any subject that relates to what scripture teaches us as to God’s ways and not honoring that Word in our life leads to self deception. This self deception comes by reasoning contrary to the Truth of God’s Word. This is exactly what king Saul did after being clearly directed by God to deal with and wipe out the Amalekites for what they had done to God’s people.
When Saul was told by God through the prophet Samuel to go and wipe out the Amalekites, Saul took his men and went to battle. But Saul spared king Agag, the sheep, the oxen, and all that was good. God then spoke to Samuel and told him that He regretted making Saul king for he had not obeyed God’s Word. Samuel was sent by God to deal with Saul. When Saul first saw Samuel he declared that he had fully obeyed the Lord. Samuel then asks about the sound of the sheep and oxen in the background, and why king Agag was with them still alive.
Saul blamed the people for this disobedience saying they wanted to sacrifice them to the Lord. When we are no longer obedient to the Word of God and confronted by spiritual leadership we often think we have obeyed God, but when proven wrong we may even begin to put the blame on others around us. Don’t just hear what God’s Word says, be diligent to obey His Word. Don’t allow human reasoning to lead you astray from the Truth. As James 1:25 tells us, those who do what scripture teaches, they will be blessed in what they do.
