Psalm 49:6-9 “They that trust in their wealth, and boast themselves in the multitude of their riches; None of them can by any means redeem his brother, nor give to God a ransom for him: (For the redemption of their soul is precious, and it ceaseth for ever:) That he should still live for ever, and not see corruption.”
We can tell what we trust in by what we boast in. Whatever we think really completes us as a person is what we brag about. So if we spend all of our time bragging about our possessions, or our children, or our house, or whatever, that is what our heart is really trusting in.
Sometimes it is easy to tell what people are trusting in because they brag out loud to most people they meet. But others only brag about it silently to themselves. Nevertheless, what we boast in, whether in public or private, is what our heart is really trusting in to save us and complete us.
Many people have a “disconnect” in their relationship with God. With their head they believe in God but with their heart they trust in themselves. They know things about God but they don’t really know God. They talk about God and what Jesus did for them but their lives really don’t reflect a daily reliance upon God to provide for them.
I heard a minister say one time that while counseling a teenage girl he realized she was quite depressed and downcast. He tried to encourage her with the fact that God loves her, that Jesus died for her, that God lives in her through faith in Christ. But the girl finally stopped him and said, “Yes of course, but what good is all that if no boy likes you?” That is a perfect illustration of what I am talking about.
Whether we want to admit it or not we are very much like that young lady. We know in our head that God loves us, and we have an understanding of the great work of redemption completed by the Lord Jesus Christ but in our heart we say, “Yeah but what good is that if I go bankrupt or get sick or fall on hard times.” Our head knows about Salvation but it hasn’t yet worked down into our hearts.
In the verses above, the Psalmist said there are those who trust in their wealth. And because they trust in their wealth they boast in their wealth. But the reality is wealth cannot save you. Even the richest man cannot redeem himself or his brother by his great wealth.
There is only one thing that can save us. There is only one thing that can complete us. And that is to be in a relationship with God through Jesus Christ. This is what we were made for and this is the thing without which we are lost and incomplete.
In the Garden of Eden mankind lost his relationship with God through disobedience. But years later, Jesus made a way for us to be in a relationship with God through His own obedience. Now we have the opportunity to be right with God. And now we can be what we were created to be. All the desires of our heart can be met by God who comes to live in us through faith in Jesus Christ.  
If God is what really saves us and completes us as people then we need to spend our time boasting in God. We need to become masters of bragging about what God has done for us. Now to be clear, let us not be counted among the arrogant who condemn others while blessing themselves. But let us be those who preach the Gospel to our own selves and really trust in God at the level of our hearts.  God said through the prophet in Jeremiah 9:23-24 “Thus saith the Lord, Let not the wise man glory in his wisdom, neither let the mighty man glory in his might, let not the rich man glory in his riches: But let him that glorieth glory in this, that he understandeth and knoweth me.”
Paul said in Galatians 6:14 “But God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world.” We have something to really brag about. We have something to boast in, something to glory in. That is our relationship with God through Jesus Christ our Lord and Savior.
Take the time to listen to your own heart. See what it is that you boast in. Then once you find it, leave it behind. Stop finding your fulfillment and purpose and satisfaction in money or health or love and start finding it in God. This is real Repentance. Turn away from what you think completes you as a person and let God complete you. Cast all your desires and cares and love upon Him for He is the “lovely source of true delight” and “at His right hand, there are pleasures forevermore.”
