From the Sept. 20th Today God Is First devotional (http://www.todaygodisfirst.com/):
'There are good things we can do, but only God-things we should do.
What seems good in our eyes may be an abomination in God's eyes. For instance, if you decide to build an orphanage but God has never directed you to do so, then God will not see that work as good; it was born out of your own strength, even though it was a "good work."
The most difficult challenge a Christian workplace believer will ever have is to know what things to be involved in and what things not to be involved in. Many workplace believers have a great ability to see opportunity. What appears to be a "slam dunk" may come back to haunt us if God never ordains us to enter that arena. There are many good things we can be involved with. However, there are God-things we are supposed to be involved with.
God's ways are not our ways. The most important quality God desires to develop in us is our dependence on Him and Him alone. When we begin to make decisions based on reason and analysis instead of the leading and prompting of the Holy Spirit, we get into trouble with God.'
Winners learn the difference between "good things" and "God-things."
