Moreover, we had human parents to discipline us, and we respected them. For they disciplined us for a short time as seemed best to them, but he disciplines us for our good, in order that we may share his holiness. Therefore fear, that involves discipline, is part of the sanctifying process of the soul. When the believer has reached a higher level of holiness, the fear fades away, it being replaced with true love in Christ. In other words, no bending the rules.
Perseverance is necessary, right to the end.
Then, Moses commanded to remember in their hearts that God is One and that they must love God with all their hearts, with all their souls, and with all their might. This is a total consecration to God, living for God, living with God, and living through God. Dwelling within the believers through His Holy Spirit, every thoughts, words and action of the believers must be holy as God is holy. The believers must shine in love as God is love. That is being in perfect communion with God.
