For I am Jehovah your God: sanctify [make holy, behave holy] yourselves therefore, and be ye holy; for I am holy: neither shall ye defile yourselves with any manner of creeping thing that moveth upon the earth. Leviticus 11:44 ASV
For God called us not for uncleanness, but in sanctification [holiness]. 1 Thessalonians 4:7 ASV
Sanctify [make holy] them in the truth: thy word is truth. John 17:17 ASV
If we could have been saved with one sin (Ezekiel 33:13), having repented, there would be no need for YHWH Elohim the Creator of all things to become flesh, to live without sinning, to die, and to claim victory over death to secure our victory unto immortality when God Father raised Him out of the dead ones. Death would not exist anyway if we could carry one sin and be excused or sanctified with the sin.
Thus, logically, we must be free of sin, without sin, be holy to be sanctified by Jesus, so He can put His seal of grace on us to save us for God Father. Think about it!
In other words, our Redeemer, Saviour, and Shepherd YHWH is telling us that, as it is written, 'Be ye without sin, for I, Yehoshua Messiah YHWH, the 'I AM', am without sin, as My Father is without sin and all heaven (Matthew 6:10)'. Leviticus 19:2.
