You are amazing, you still do not get it.
When you use the term MUST, it some you do to be right with God, which is a FALSE DOCTRINE.
When you use the term WILL, it is HE WHO DID SOMETHING TO CHANGE YOUR HUMAN SPIRIT.
THAT IS THE DIFFERENCE BETWEEN A WORKS RIGHTEOUSNESS FALSE THEOLOGY,
AND THE GOSPEL ACCORDING TO JESUS.
Look at the way Young's Literal Translation words that verse you quoted:
2 Timothy 2:19 (YLT)
[SUP]19 [/SUP] sure, nevertheless, hath the foundation of God stood, having this seal,
`The Lord hath known those who are His,' and `Let him depart from unrighteousness-
-every one who is naming the name of Christ.'
2 Timothy 2:19 (CSBBible)
[SUP]19 [/SUP] Nevertheless, God's solid foundation stands firm, bearing this inscription:
The Lord knows those who are his, and let everyone who calls on the name of the Lord turn away from wickedness.
2 Timothy 2:19 (NKJV)
[SUP]19 [/SUP] Nevertheless the solid foundation of God stands, having this seal:
"The Lord knows those who are His," and,
"Let everyone who names the name of Christ depart from iniquity."
2 Timothy 2:19 (ESV)
[SUP]19 [/SUP] But God’s firm foundation stands, bearing this seal: “The Lord knows those who are his,” and, “Let everyone who names the name of the Lord depart from iniquity.”
When they insert MUST in the verse they change what the the original language said. When it sticks with the original language wording, the LET becomes, something we will WANT TO DO, instead of your HAVE TO DO.
If you want to be Born Again, you will have to come to HIM, mourning your sinning your utter sinfulness, and being willing to Surrender every bit of yourself, out of LOVE FOR HIM, giving HIM the right to change anything and everything in you that HE WANTS TO CHANGE. That includes the pride you have in what you think you do to be right in HIS EYES.
