Errors Some Christians Believe: Proverbs 22:6 Promises Godly Children
Proverbs 10:27 says, "The fear of the LORD adds length to life, but the years of the wicked are cut short."
So we can determine a man's godliness by the length of his life. Right?
Proverbs are the divinely inspired Word of God, but Proverbs defines itself as a book of wise principles, not promises.
If a particular Proverb is a promise, it will be confirmed as such elsewhere in Scripture.(1)
Perhaps the most misused Proverb is 22:6 - "Train up a child in the way he should go; even when he is old he will not depart from it."
We cannot determine a man's righteousness by the length of his life nor can we determine the quality of parenting by an adult child's choices (Proverbs 22:6). To do so causes guilt, confusion and error.
Proverbs 22:6 contains a principle which often proves true, but it's not a promise. (See Ezekiel 18:20).(2)
Calling it a promise is a misuse of God's Word (2 Timothy 2:15).
(1) For example: Proverbs 3:5-6 says God directs those who trust Him, something confirmed throughout Scripture (e.g. Romans 12:2; John 16:13).
(2)Often children of godly parents become godly, but not always. Each man is held responsible for his choices. He cannot blame them on his parents. Parents are responsible to God for how they parent, but good parenting does not guarantee godly offspring, nor does bad parenting guarantee ungodly offspring.
