Tithe does not mean to offer 10% to God and keep 90% for yourself.
Tithe does not mean to return 10% to God and then add the amount you want to offer.
Tithe means using 10% of your earning to support the church and its ministries, and 90% to support your home and your ministries. Both sides shall have the same goal to do the will of God. In other words, it is not about 10%, but 100%.
Look, God created all things. Does He only deserve 10%? This is a very simple question. Even our power, opportunity, health, and even the air of breathing are His. Should He only get 10% or 20%, and then we deserve 90% or 80%?
The Bible says that we were bought with a price, which is Jesus. God gives us Himself. What He wants is not part of us, but the whole life, including our money and time. What God wants is our hearts. Paul said,
“For none of us lives to himself, and none of us dies to himself. For if we live, we live to the Lord, and if we die, we die to the Lord. So then, whether we live or whether we die, we are the Lord’s.”Romans 14:7-8
Since we call Jesus “Lord,” we are not our own Lords. What we should do is to loyally use the resources (time, money, talents) that God has entrusted to us to do His will. (Matthew 25:14-30, 28:18-20; Luke 19:11-27)
“One who is faithful in a very little is also faithful in much, and one who is dishonest in a very little is also dishonest in much. If then you have not been faithful in the unrighteous wealth, who will entrust to you the true riches? And if you have not been faithful in that which is another’s, who will give you that which is your own?”Luke 16:10-12
So, what are the true riches? Aren’t those that can be kept in the eternity? Jesus says “that which is your own.”
“Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal, but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal. For where your treasure is, there your heart will be also.”Matthew 6:19-21
