Read Proverbs 15.
The best things in life are free...and come at a high cost.
In the middle of this chapter, are two verses that declare somethings that are "better" for life. Each is free, in that they do not require any money. Yet, each of them bears a high price.
1. Holding God in reverence. (v.16)
Repeatedly in the book of Proverbs we are admonished to fear the LORD. This is the starting point of all wisdom (1:7) and it is the requirement for the path of life. Experiencing such a relationship with the Living God is free by His grace. It is His gift to us (Romans 6:23). Yet, it comes at such a price we cannot imagine. The sinless Son of God took our sin upon Himself so we might have His righteousness (2 Corinthians 5:21). This, according to wisdom, is better than having all the money in the world.
2. Loving family at home. (v.17)
The household income may be meager. One's financial ability may be limited to an extreme. But expressing and receiving love is free. Yet, it costs us repeatedly in the daily sacrifices in every way. Maintaining a loving relationship with family involves giving up what we want for the needs of the people God has given to us. It changes the use of our time, deflates our egos, changes our plans, and will drain what finances we do have. It will drive us to our knees for intercessory prayer. True love is more than an emotion. What separates love from lust is commitment. When one is willing to commit themselves for life to their family and their needs, it will be better than all the other provisions one could possibly give to their family.
