Some one should go through the book of
Psalms as count how many
"O LORDs" there are in the book of Psalms.
I think
"O" or
" OH " OPENS up the heart.
"O Lord Jesus" should be said with your heart wide open to Jesus.
In the heat of temptation you can access the empowering grace of the Holy Spirit by calling. Jesus is available. Jesus Christ is available. So we call on Him out of a pure heart.
A Pure Heart I think means a SINGLE heart. Pure in motive wanting one thing - to TOUCH God. The Bible encourages us to be PURE in wanting a SINGLE matter - to touch Jesus, to contact Jesus, to fellowship with Jesus.
So Paul told Timothy to be with those who CALL UPON the name of the Lord out of a pure heart.
" But flee youthful lust, and pursue righteousness, faith, love, peace with those who call on the Lord out of a pure heart." (2 Tim. 2:22)
There is NOTHING in this passage teaching that you have to WAIT until have fully obtained faith, fully obtained love, fully obtained peace, or have fully fled youthful lust
BEFORE you are qualified to call
"O Lord Jesus!".
There is no need to WAIT until you feel qualified to CALL. In the fleeing you call
"O Lord Jesus!"
In the pursuing faith you call
"O Lord Jesus! Lord Jesus I pursue You Lord."
In pursuing righteousness you can CALL -
"O Lord Jesus!! I pursue You Lord as my righteousness. Constitutes me RIGHTEOUS Lord."
In pursuing peace, love, with all those who are pursuing - CALL on His name. TOUCH Him. Pursue BY calling.
Flee ... BY CALLING.
