Before Jesus left this Earth, He gave us some parting words. He said to go into all the world and preach the gospel to everyone (Mark 16:15). This is our "Mission". So, how do we do that? - Sharing The Gospel.
God made a promise to Abraham that He would make him a great nation and that all the families of the earth would be blessed. So, 25 years later, the promise was fulfilled in Isaac! The scripture uses this story as an example, to remind us that it's through faith & patience that we inherit God's promises. - Keeping The "Switch of Faith" Turned On.
