This sermon on Galatians 6:6-10 by Pastor Tom helped me.
He pointed out that we usually spend our resources (like money, time, energy) on ourselves or someone we love. We sow to the flesh. If we invest those things in God’s kingdom, we sow to the Spirit and reap eternal rewards instead of earthly gain which passes away.
Thinking about that idea has helped me be more aware of what I’m doing with the time, energy, and financial resources God makes available to me.
