Matthew 5:17 Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfil them.
Sometimes I hear people describe how Jesus re-wrote the rulebook... He came to uphold it, not re-write it!
Jesus wanted us to see the promises of God come true so we would have more hope for the promises still to come true.
Jesus knows how much we depend on proof for so many things in life, so He fulfilled many promises in person.
We just have to cling on to the hope we now have in His promises of our futures.
