The anti-Christ is referred to as the "lawless one." He does not regard the law.
Now if a person has come to know Yeshua, will he obey the law, or be lawless.
For once we have known the grace of Yeshua and deliberately sin, we are recrucifying Him.
Now, I believe Yeshua, and, YES, I have succumbed to sin since I know Him, but I do not sin deliberately, for I have always observed His law since I have had power of reason thereof. I live in grace, and I remain in grace because I honor God by obeying Him.
Ask youself, do you honor Yeshua by your obedience? If you want to obey Him, knowing you are not perfect, nor is any man, then you will do what He has shown is His will, obey His law. Grace does the rest as long as you believe Yeshua is your Way, your Truth, and your Life. He is Mine forever, Praise Yeshua, amen.
