What does Proverbs 7:2 mean?

Jesus said, "It is written, 'Man shall not live by bread alone, but by every word that comes from the mouth of God'" (Matthew 4:4). Solomon connected his commandments to life. His son would experience a significant life if he obeyed Solomon's commandments. As with other statements in the book of Proverbs, this is a statement of general truth, not an absolute guarantee. This is similar to how a doctor might say, "eat healthier and you will live longer."

Sinners receive eternal life by responding in faith to what God's Word says about Jesus: that He is the Son of God and the only Savior (John 3:36; Romans 10:9–10; 1 Timothy 1:15). Also, abundant life is offered to all who believe on Jesus (John 10:10).

Solomon also urges his son to guard these teachings as the "apple of [his] eye." This comes from the Hebrew term i'son, referring to the pupil: the center of the eye. This is a highly sensitive and an extremely valuable part of the body. When a threatening object approaches the eyes, the eyelids close quickly to protect the pupils. Guarding our lives from evil by keeping God's Word is essential.
