“This keeping of our hearts for singular loyalty to God is to be done in every area of our lives, whether it refers to maintaining sexual purity, or as we will see in chapter 6, putting up financial security for another, maintaining good stewardship, or watching even our speech and way of life. So, the topics of sexual purity, finances, stewardship, and conduct are all areas that we need to be careful to guard our hearts for the Lord practically and diligently. All of these areas—even all of life—are included in living out the wisdom of God, which is built on fearing the Lord, obeying His commands, and cherishing His Word in our hearts for as long as we live.”
