Deuteronomy 7

15 The LORD will keep you free from every disease. Here Moses states that if the Israelites follow God’s laws (verse 12), they will not get any disease. Some people say that if we get a disease, it’s proof we have sinned or have no faith (which is also a sin). These people thus add guilt to the physical burden the sick person is already bearing.

Moses’ statement here seems to go against common experience. Devout believers get sick; tiny infants get sick; at some point everyone gets sick and dies. People do not “just die”; something goes wrong. One or another vital organ stops working because of some disease process. So how are we to understand this verse?

Jesus taught that disease is not always caused by sin or unbelief; sometimes God allows a physical ailment to occur in order to achieve some broader good (John 9:1–3; 2 Corinthians 12:7–9). God may want to test us or discipline us (see Exodus 15:25–27 and comment).

Furthermore, none of us can perfectly follow all of God’s commands—especially those commands that relate to attitudes such as covetousness, anger, ingratitude, or a grumbling spirit. So the promise in this verse of total freedom from disease can never be fully realized; we can never completely meet the conditions. For example, in the book of Leviticus, it is acknowledged that there will be infectious skin diseases, and detailed instructions are given to ensure that they do not spread (see Leviticus 13:1; 14:1 and comments).

It is best to understand this verse as stating a general principle. The more we follow God’s laws the healthier we will be. Sins and sinful attitudes definitely cause many kinds of illness; this is a widely known medical fact. So in this verse, Moses is telling us that if we avoid sin, we can also avoid disease. But let us always keep in mind that there may be exceptions to this principle; God has purposes we are not always aware of. And let us never assume that a person’s sickness has been directly caused by sin, or that if the sick person would only “have faith” he or she would automatically be healed. Much harm is caused by “friends” who say such things.²⁷

25–26 Here is a warning not to covet the gold and silver that may be contained in the images of false gods: such images must be destroyed completely and the gold and silver presented to the Lord. To take such gold and silver for oneself would ensnare the greedy person and lead to his destruction (see Joshua 6:17–19; 7:1,2026). Everything connected with a false god was detestable to the Lord (see Leviticus 11:11,13,43). Those who love God must love what He loves and detest what He detests.
