By faith Abraham, when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out, not knowing whither he went.
Abraham was asked to take some pretty big steps in the darkness. It’s easy for us, from our perspective, to see that God was asking Him to take steps into or toward His inheritance.
But Abraham couldn’t see it that way. All he saw was the dark, open road ahead. All he saw was leaving behind security (for many different reasons at many different times). All he saw was unknown.
But he went out, not knowing where he went.
That’s a true exercise and manifestation of faith. God saw the inheritance. Abraham did not. He just had a promise of the inheritance.
When God gives us a promise of the inheritance, whether it’s the general promise to all faithful followers or the specific promises made to you in priesthood blessings and the whisperings of the Spirit, they are just as sure. We don’t always see the how or the when, but we can trust the promise.
That’s faith. And that’s what’s required to not only obtain the promise, but to retain the peace while taking those unknown steps. He has promised He will lead us to our inheritance. Our job is to trust and step forward into the unknown.
