The Bible teaches that everything we do should be done for the glory of God. (See 1 Corinthians 10:31). The “everything” obviously would include the time that God gives to us.
The Core Idea
In order to make the best use of our time and therefore glorify God we must understand the concept of a core idea. Matt Perman writes in “What’s Best Next: “The best way to understand a subject is to understand the core idea – the governing concept that goes to the heart of the matter and holds everything else together.”
As an example God’s commands can be summed up in a core idea. When Jesus was asked what was the greatest commandment he answered by saying “love God with all your heart and love your neighbor as yourself”. Then he went on to say “On these two commandments depend all the law and the prophets.” What was Jesus doing? He was summarizing the entirety of the Old Testament Law into a single principle, into a core idea.
