There is a lot of confusion around the topic of tithing.
Is it really 10%? And is that based on net or gross income? Those technical details probably aren’t the key takeaway from Jesus teaching. Rather, we think He wanted us to understand that tithing was not instituted for God’s benefit, but for our benefit. God doesn’t need our money.
So why does He ask us to give a tithe to Him? It is to teach us how to keep God first in our lives and how to be unselfish people. Unselfish people make better husbands, wives, friends, relatives, employees and employers. God is trying to teach us how to prosper over time. daveramsey.com
Giving is a reminder to ourselves of who owns our gifts and resources. Giving is an act of praise and worship. Dave Ramsey also mentions that giving is a way of engaging in spiritual warfare - Malachi 3:11.
The more we give, the more our heart is shaped like Christ’s. God is a giver – John 3:16. We are happiest and most fulfilled when we are serving and giving.
