I've been asked how much the widow's offering is worth today. There are at least two problems with the question. First, it entirely misses Jesus' point. The widow's offering was a sacrifice, while the offerings of others were apparently not.
Is the Kingdom of Heaven the same as the Kingdom of God? Are they different? If they're the same, why do different books of the Bible use different words to describe the same thing? What does each phrase mean? The Bible is complicated. While it looks like a single book, it's really a group of 66 unique books.
