Well that would be nice if it were true. but that means 24/7 you never entertain a wrong thought, never have 1 ungodly word or never do something wrong ever! You and another here justify imperfection by saying you did not do it willfully. If you know it is a sin and do it it is willful. And there is forgiveness in God purchased by the blood of Jesus.
You have been given a batch of bad teaching! Jesus teaches us to forgive 70X7 if our neighbor sins against us, and you have him as an ogre who tosses you out of trhe kingdom the first time you sin and know it is sin. Sorry, but that is not the one true God!
How is it that you don’t understand? Those who belong to Messiah Jesus have crucified the flesh with the affections and lusts.
Galatians 5
24 And they that are Christ's have crucified the flesh with the affections and lusts.
