Psalm 135 says it this way:-

“The idols of the nations are but silver and gold,
The work of man’s hands.
They have mouths, but they do not speak;
They have eyes, but they do not see;
They have ears, but they do not hear,
Nor is there any breath at all in their mouths.
Those who make them will be like them,
Yes, everyone who trusts in them.”

This is the danger. To trust stuff.
The Psalmist says if you trust stuff or money then you become a lifeless object. Why? Because of this vital truth. You and I become like the things or people we trust.

This is one of the many reasons Jesus says to put your confidence in Him. To trust Him. As you grow in your trust you grow more like Jesus. We get profoundly and unavoidably changed by what we look at.

For trust is intimately connected to love.  James K.A. Smith writes, “To be human is to love, and it is what we love that defines who we are.” Simply put, as you begin to love Jesus you become more like Him and as you trust Jesus you become more like Him.

This is why John Stott, in his last words at the Keswick convention said it this way:- “God wants His people to become like Christ. Christlikeness is the will of God for the people of God.”

For we become the sum-total of what we trust in.
