"Therefore, this verse is a promise to those who believe on Jesus to the extent that they are willing to change their actions accordingly and confess Him as Lord (God) with their mouths so that they might be saved."

That is a false gospel. If lost sinners must be "willing to change their actions accordingly" to be saved, then that is a works-based salvation. As with other false prophets, Wommack makes the grave mistake of putting-the-cart-before-the-horse. The willingness to change is a FRUIT, or result, of genuine repentance; and not a part of saving faith. Wommack correctly recognizes "repentance" in his commentary on Matthew 3:2 as "a change of mind." However, he then perverts the definition of Biblical repentance by adding works...

"Repentance is simply a change of mind accompanied by corresponding actions (Mt. 3:8; Jas. 2:17)."

Wommack is incorrect. Repentance unto salvation does NOT need to be "accompanied by corresponding actions." Wommack wrongly defines repentance as including "actions." What actions are Wommack vaguely referring to? Clearly, he is implying that a person must depart from their sinful living. Wommack's commentary on Romans 10:9 states that a person must "change their actions" to be saved. Again, he states...

"Therefore, this verse is a promise to those who believe on Jesus to the extent that they are willing to change their actions accordingly and confess Him as Lord (God) with their mouths so that they might be saved."

If Wommack were correct, which he is not, then a lost sinner could not be saved unless he or she were willing to stop committing sin. This is known as the heresy of LORDSHIP SALVATION, and it's of the Devil. Wommack plainly states that believing on Jesus Christ is NOT enough for salvation, unless it is a belief that includes "changing" one's "actions." This violates the plain teaching of Romans 4:5, "But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness." Biblically, a person DOESN'T have to change a thing to be saved. God does the changing. That's why He saves us, so He can cleanse us from all unrighteousness (1st John 1:9). Again, carefully notice that Wommack requires a sinner to be "willing to change" as a prerequisite to salvation. A willingness to change is the result of true repentance; and not a part of saving faith. Salvation is without works and a man's faith is COUNTED for righteousness. This is the simplicity that is in Christ.

Every heretic who teaches Lordship Salvation deceitfully claims to believe that salvation is 100% by God's grace; but they do not. If they truly believed that God's salvation is unconditionally offered to mankind on the basis of Christ's blood sacrifice alone, then they'd stop teaching that sinners must be "willing to change" their life and stop living in sin to be saved. The Biblical truth is that sinners don't have to "change their actions" to be saved. Wommack is teaching a false gospel which requires human effort in order to be saved. Salvation is of the Lord.
 

Conclusion

Although some people will no doubt allege that it's merely a matter of semantics, I can only go by the statements a man makes concerning salvation. Andrew Wommack plainly writes in his commentary regarding Romans 10:9 that a sinner must believe on the Lord "TO THE EXTENT THAT THEY ARE WILLING TO CHANGE THEIR ACTIONS." That is a false gospel. Any amount of belief (i.e., trust) upon the Lord Jesus Christ as the Savior is enough to be saved. God does NOT require a certain degree of faith to be saved, just enough to call upon the name of the Lord (Romans 10:13). Wommack's false gospel invalidates the faith of those who are not willing to change their actions. This is nothing less than the damnable heresy of Lordship Salvation.
