1 Nephi 4:1-2

God is willing to help you in your trials, but following him/his commandments will make the blessings bestowed upon you more bountiful.
Where God wills, you can succeed.

"...let us be faithful in keeping the commandments of the Lord; for behold he is mightier than all the earth, then why not mightier than Laban and his fifty, yea, or even than his tens of thousands?"

"Therefore let us go up; let us be strong..."
