James 2:2 

“For if a man wearing a gold ring and fine clothing comes into your assembly, and a poor man in shabby clothing also comes in.” God shows no partiality: rich and poor alike are called into the Kingdom. And both rich and poor alike have something to contribute to the Kingdom in accordance with the callings God has given them in their lives. This is why both the Old and New Testaments talk about proportional giving – that is, giving a proportion of our income to the Lord’s work. This makes it possible for rich and poor alike to have the honor of supporting God’s work.
