Jesus said, "…lay not up for yourselves treasures on earth…" Earthly treasures are things that make us appear successful, comfortable, or proud — clothes, property, money, conveniences, status, and all the modern comforts people feel they must have. Jesus wasn't just warning against materialism — He was warning against the selfish mindset behind it. So when Jesus said, "…but lay up for yourselves treasures in heaven…" we must consider that a selfish mindset is just as wrong in spiritual things as in earthly things. We cannot think of "laying up treasure in heaven" as personal gain or spiritual profit. The real heart of laying up treasure in heaven is tied to the greatest commandments, which are to love God, and to love your neighbor as ourselves. Treasures are not laid up in heaven by "taking care of myself spiritually." Instead, it comes from serving others, sacrificing, giving, helping, and seeking their good — not our own. We are laying up treasures in heaven when we are serving others, as part of the kingdom of God, and for the glory and honor of God, and not for ourselves.
