8 And these things have I written, which are a lesser part of the things which he taught the people; and I have written them to the intent that they may be brought again unto this people, from the Gentiles, according to the words which Jesus hath spoken.
9 And when they shall have received this, which is expedient that they should have first, to try their faith, and if it shall so be that they shall believe these things then shall the greater things be made manifest unto them.
10 And if it so be that they will not believe these things, then shall the greater things be withheld from them, unto their condemnation.
The heavens are open. Those who believe the things they have been given in the scriptures are promised more. There are things that we do not understand, but as we apply the principles of the gospel in faith, those things can be made clear to us. What is intriguing is that we don't even know what "greater things" have been withheld. But the promise is clear that if we believe what we have been given that "greater things" will be revealed.
