Some sell out their own growth in faith, pushing God out of the picture of their lives where He won't disturb their pursuit of pleasure and greed for gold. James takes aim particularly and powerfully at those who push God aside in favor of a good sales report or climbing profit margin. He writes that instead of making great plans for selling and trading today, tomorrow and next year, they should seek and recognize God's will in their plans and lives. James is not suggesting the simple addition of some word formula to the plans they are already making. Like Jesus, James urges us to a radical faith that gives God a radical place in our lives.
Tomorrow is too late.
But the eye that blinks, THAT is something. A span of life is nothing. But the person who lives that span, HE or SHE is something. He or she can fill that tiny span with meaning, so its quality is immeasurable, though its quantity may be insignificant. I didn't understand the word at first.
