Logically, then, wisdom​—the opposite of foolishness—​would be one evidence of maturity. Spiritual maturity is not determined primarily by age but by a person’s healthy fear of Jehovah and readiness to obey his commands. (Ps. 111:10) Young ones who are reasonably mature spiritually are not “tossed about as by waves and carried here and there” by their desires or by pressure from their peers. (Eph. 4:14) Rather, they are making progress in having “their powers of discernment trained to distinguish both right and wrong.” (Heb. 5:14) They demonstrate that they are progressing toward maturity by making wise decisions. That kind of wisdom is necessary for salvation. (Prov. 24:14) Therefore, make sure that you clearly state your Bible-based values to your children. By your words and by your example, let them know that the values found in God’s Word are also your values.​—Rom. 2:21-23. w17.12 20-21 ¶12-13
