There are many demands on our resources, all of them requiring our attention. Yet throughout the Scriptures God talks consistently about what it means to be generous toward God and others with our resources. God calls us to diversify.
1 Timothy 6:17–19 (ESV) 17 As for the rich in this present age, charge them not to be haughty, nor to set their hopes on the uncertainty of riches, but on God, who richly provides us with everything to enjoy. 18 They are to do good, to be rich in good works, to be generous and ready to share, 19 thus storing up treasure for themselves as a good foundation for the future, so that they may take hold of that which is truly life.
