What do we really give to God? Do we keep anything from God?
Read Acts 20:35
All that we have IS HIS and WAS HIS and will always BE HIS. The time we spend playing computer games rather than searching for more understanding through the same source IS HIS. The things we do, like writing, crafting, singing, playing an instrument, cooking, baking, career or job activities ARE HIS. Every penny of the money we have, earn or inherit IS HIS.
If we are holding back any part of the ALL that IS HIS we need to ask Him to make us aware. Pray that we will be made aware of what is needed in the Kingdom. Our return of His provision let those around us know that WE ARE HIS! (John 13:35)
