What is a freewill love offering? It is generally an exchange of money or gift from the heart in appreciation for the service received. It shows gratitude and acknowledges that you have found value in what you have received.
Why would one do this kind of business in this day and age?
2 Corinthians 9:6-7 The Message Bible Translation
Remember: A stingy planter gets a stingy crop; a lavish planter gets a lavish crop. I want each of you to take plenty of time to think it over and make up your own mind what you will give. That will protect you against sob stories and arm-twisting. God loves it when the giver delights in the giving.
I am a firm believer in this, that one must engage and actively participate in their own life, and when you do, you can feel like a contributor in your outcome; appreciation for what we contribute is a valued gift. You can't buy God, yet one thing is for sure He has given us each other, and we are the most incredible resource on Earth.
