I learned recently of a film strip, the first picture of which showed a small boy playing with a sailboat and a train. All time belongs to God. We have time only as a stewardship. God may require an accounting of us at any moment.
People say they can do what they want with their own time.
They forget that the sequel to life is God's. We keep the seventh-day Sabbath according to the commandment. It is the Lord's day. God is the Lord of time as He is the Lord of the Sabbath. The same is true with the wealth we have.
