Maybe God wants us to trust Him with the unknown of the better rather than resting in the comfort of the good. Maybe one choice might bring greater rewards. Either way it seems that this better choice often requires sacrifice. For example, a better choice for your family’s income might mean a smaller house, having to sacrifice material things you enjoy. Or staying home with your kids, having to sacrifice a career you have worked hard to achieve. Or even buying organic food, having to sacrifice electricity for your home (OK organic is not that expensive.)
My point is that life just isn't always black and white. There are shades of grey. I really think there can be good and better with neither being necessarily sinful. I pray God would give us both wisdom and strength in our decisions this day, especially those choices between good and better.
Keep at it, friend.
