Jacob 4:6 - 4:10
Jacob 4:6 Wherefore, we search the prophets, and we have many revelations and the spirit of prophecy; and having all these witnesses we obtain a hope, and our faith becometh unshaken, insomuch that we truly can command in the name of Jesus and the very trees obey us, or the mountains, or the waves of the sea.
As they study and ponder the scriptures they have, their faith in God becomes so strong that nothing can deter them from living as they should. The scriptures, prophets, and revelation all combine to give them a foundation that cannot be destroyed and if they should feel the need to move mountains or perform any other miracle they could do it.
Jacob 4:7 Nevertheless, the Lord God showeth us our weakness that we may know that it is by his grace, and his great condescensions unto the children of men, that we have power to do these things.
But even with these powers, the Lord does show them their weaknesses and where they must improve to continue in their progression. It is only the love of God that such things would be revealed to them and not because of anything they did to earn such consideration.
Jacob 4:8 Behold, great and marvelous are the works of the Lord. How unsearchable are the depths of the mysteries of him; and it is impossible that man should find out all his ways. And no man knoweth of his ways save it be revealed unto him; wherefore, brethren, despise not the revelations of God.
As Jacob accesses the things of God, he marvels that God would even consider man, considering his low state in the universe of glorious beings. Being in this fallen state, it is only by revelation, scriptures and prophets that such things are made known to man. There is no way to find out about the heavens or the mechanics of the universe save it be revealed to him from external sources.
Jacob 4:9 For behold, by the power of his word man came upon the face of the earth, which earth was created by the power of his word. Wherefore, if God being able to speak and the world was, and to speak and man was created, O then, why not able to command the earth, or the workmanship of his hands upon the face of it, according to his will and pleasure?
The earth was created by God for the children of men. Man, himself, is also the creation of God. If God can do these incredible things, then why can He not do with the earth or all things on the earth anything He sees fit to do.
Jacob 4:10 Wherefore, brethren, seek not to counsel the Lord, but to take counsel from his hand. For behold, ye yourselves know that he counseleth in wisdom, and in justice, and in great mercy, over all his works.
Because of this, do not try to tell the Lord what He should do in relation to the earth or its inhabitants. He knows infinitely better than we do what we need. He knows how to manipulate events and men to get the results He wants. So we should be seeking council from Him not the other way around. He loves us and will only do that which is of the greatest benefit for us each individually and collectively.
