This is my story on the subject of tithing (giving).
For many years, like so many here, I looked for excuses not to tithe. There are many scriptures quote here in this thread that provided me with excellent excuses, and I claimed at least one every time I got paid. I always gave a little here or there, and put a few dollars into the youth ministry, but it was a drop in the bucket to what God expected of me.
That all changed many years ago. I was making out my checks to pay my monthly bills, when I heard this voice in back of me saying "where's mine". I looked around, saw no one, checked my checks, and mailed them. This went on for several months until I read Malachi 3:8-10.
Mal 3:8 Will a man rob God? Yet you have robbed Me. But you say, In what have we robbed You? In the tithe and the offering!
Mal 3:9 You are cursed with a curse; for you are robbing Me, the nation, all of it.
Mal 3:10 Bring all the tithe into the storehouse, so that there may be food in My house. And test Me now with this, says Jehovah of Hosts, to see if I will not open the windows of Heaven for you, and pour out a blessing for you, until there is not enough room. MKJV
I stopped looking for a reason (excuse), and started to tithe. This is my first priority every month. I have always had enough to pay my bills, and very few times has a month passed that I haven't added money to my savings. When a need arises, I take it to Jesus. He always provides me a way to meet it.
If you are one of those who continuously look to the scriptures for an excuse to not give on a regular basis (tithe), stop. Enjoy the blessings that God provides. There is nothing like the pleasure I get when a young couple dedicates their lives to Christ and a few years later dedicate their children to Christ. I will continue to tithe until God takes me home. I hope that everyone here will commit to a regular giving routine, and stop worrying about whether it is required or not.
