The answer is found in Lesson 5 of Journey.
Would you like to learn one on one what the Bible says about giving and many other topics as well?
For a Disciple, true Biblical giving goes much further than giving money. It is turning over complete control of your life and resources to Jesus Christ; our time, talents, skills, resources, etc.
When we give financially we are getting the Gospel to the unreached. If God has control of our lives, He will have control of all we have as well. And tithing is a beginning point in giving.
When tithing is given in the Bible, it’s 10 percent of what we earn; the gross income.
