Psalms 119:99-100
 I have better understanding and deeper insight than all my teachers, because Your testimonies are my meditation.
I understand more than the aged, because I keep Your precepts [hearing, receiving, loving, and obeying them].

Romans 12:2
Do not be conformed to this world (this age), [fashioned after and adapted to its external, superficial customs], but be transformed (changed) by the [entire] renewal of your mind [by its new ideals and its new attitude], so that you may prove [for yourselves] what is the good and acceptable and perfect will of God, even the thing which is good and acceptable and perfect [in His sight for you].

In the light of the scriptures read, 119th chapter of The Psalms and 12th chapter of Paul’s Letter to the Romans, I see that saying continually to ourselves ‘I have a sound mind’ continually will neither activate, facilitate nor develop our minds.

But according to the scriptures, we must be conscious of the word. This we can do by bombarding our minds with the Word. Get recordings of sermons, find Gospel music that is spiritual because its scriptural, be disciples of Jesus and Love rather than tradition and complacence.

This way…our minds will be renewed because the Light shines on in the darkness, for the darkness has never overpowered it.

That’s rest.

Look to Jesus by listening to the Word. Study it when you can. Listen to Christ in you all through the day. This way Everyday, Jesus is your response.
