the economy is bad, people have money on the brain, and i understand the desire for the church to be "relevant," but this is not a good metaphor. think of it: money is valuable, Jesus is really valuable, so Jesus is like money, only better! it's crass.
the idea of God as treasure is a popular motif in praise songs, and as Christians we certainly value Christ above all, but the comparisons to gold that i found in scripture were certainly more nuanced than the sign:
God's law
The ordinances of the LORD are sure and altogether righteous.
They are more precious than gold, than much pure gold (Psalm 19:9-10)
The law from your mouth is more precious to me
than thousands of pieces of silver and gold (Psalm 119:72)
I love your commands more than gold, more than pure gold (Psalm 119:127)
God's wisdom
Blessed is the man who finds wisdom, the man who gains understanding,
for she is more profitable than silver and yields better returns than gold (Proverbs 3:13-14)
faith
our faith—of greater worth than gold (1 Peter 1:7)
the blood of Christ
For you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way of life handed down to you from your forefathers, but with the precious blood of Christ (1 Peter 1:18-19)
what i found most off-putting in the Jesus-as-investment metaphor is the suggestion that Jesus exists to enrich us or to provide us with security like our IRA. of course scripture promises blessing to Christians, including salvation, grace, forgiveness, peace, and joy, but the call to discipleship is a call to deny ourselves, pick up our crosses, and follow Christ. it's a call to die to ourselves, our desires, and our sinful natures. the true Christian gospel is not the "health and wealth" gospel that is sometimes preached, where faith in Christ is an all-access pass to prosperity, riches, and wordly blessings. it may just be the opposite.
the incredible truth of the gospel is that it is only in dying to ourselves that we are able to experience life to the full, abundantly rich with all the goodness that God wants to give to us. I don't "invest" in Jesus hoping for big returns; it was Jesus who paid the heavy price for my redemption with his own life and "bids me come and die and find that i may truly live."
