Keep your heart with all diligence; for out of it are the issues of life.
All Commentaries on Proverbs 4:23 Go To Proverbs 4
Basil the Great
AD 379
Whoever, therefore, would be truly a follower of God must sever the bonds of attachment to this life, and this is done through complete separation from and forgetfulness of old habits. We must wrest ourselves from both fleshly ties and worldly society, being transported, as it were, to another world in our manner of living, as the apostle said: “But our commonwealth is in heaven.” Without this it is impossible for us to achieve our goal of pleasing God, inasmuch as the Lord said specifically, “So likewise every one of you that does not renounce all that he possesses cannot be my disciple.” And having done this, we should watch over our heart with all vigilance.
