The abiding comes after we win the mind-battles. We abide in Christ, and His Spirit dwells within us when our minds have won the thought-wars.
But it is a battle in our minds. Satan attacks our thinking. He tries to occupy our minds with trivial, physical pursuits. Christ said to not think on food, clothing, and other physical things, but look on the invisible, spiritual things.
Our spiritual growth level is determined by how much or how little of His Spirit is manifested through thinking the things that He thinks about.
Precious Sheep Of Renown 
Amen! It’s like a spiritual mind meld. God’s mind (mental disposition/mind i.e. God’s spirit/nature) to our mind (mental disposition/mind i.e. man’s spirit/nature) that is conviction. We fall away when mind melding with the evil spirit (mind/mental disposition of worldly things.
Yes we are to renew our minds in the word. The only insurance we have to not veer off the narrow path.
Blessings Always
