You are rich! If you don't believe me, check out the Global Rich List to find out how you rank relative to everyone else in the world. Chances are, you'll rank in the top 10% or so.
But remember, it's just one measure of whether you're rich...and a temporal, limited measure, at that. Here's another, more significant perspective on what true wealth is all about -
"In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, which he lavished upon us, in all wisdom and insight" (Eph 1:7-8)
In him we have obtained an inheritance, having been predestined according to the purpose of him who works all things according to the counsel of his will, so that we who were the first to hope in Christ might be to the praise of his glory. (Eph 1:11-12)
"But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ--by grace you have been saved and raised us up with him and seated us with him in the heavenly places in Christ Jesus, so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus." (Eph 2:4-8)
"Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgments and how inscrutable his ways!" (Rom 11:33)
