I believe it to be latter. After knowing the Christ.
The followers were examples of this . Thoughts, intents, such as calling down fire, dismissing the children, Peter raising his sword.
Who's the greatest in the kingdom, not liking Matthew the tax collector, doubting Jesus, Peter's denial ect.
As we walk with Jesus our minds should be transformed, our thoughts be discipline. Eyes focused.
As the Holy Spirit convicts those thoughts and things that are not of God.
As John the Baptist said.." I must decrease he must increase ".
