Why is it that when someone says something here that people don't "like" then it is twisted and turned to say what it does not? Let's look at your examples one at a time and apply what I said to it okay?
So your telling when God tells me to buy a gift for someone, its not right because its not biblical?
Why did you buy it? Was it out of Love for self or for the other person? The bible tells us to Love one another. My bet is on you doing it because you Love the other person and want to relay that Love to them. Now you may be inspired by self or God, but the gift if given out of Love is a biblical concept and is indeed consistant with the word of God. Humm, isn't that what I said the voice of God sounded like?
Or the times He told me to hold on to my tithes because He had a greater plan than I did, like giving to someone who was in dying need, its not from God?
Again, what was the motivation and did were you surprised by the person sent that needed your help. Did you struggle to give it? Sacrificial love is what the bible is all about, so again, unless I think your motive was self, which I don't, the message is biblical in nature. BTW, I wonder why so many people limit thier giving to tithing and not the sacrifical Love God has commanded us to? But alas a different topic, back to your post.
I'm sorry I'm not religious.
