And it shall come to pass, that if the Gentiles shall hearken unto the Lamb of God in that day that he shall manifest himself unto them in word, and also in power, in very deed, unto the taking away of their stumbling blocks
In the context of Nephi’s vision, this is particularly talking of the stumbling of the Gentiles due to the loss of the ‘plain and precious things’, and the potential rectifying of that if they repent when God begins his ‘great and a marvelous work’. But reading it today it also feels like there is a general principle here (also elaborated on in Ether 12). We all have ‘stumbling blocks’: our weaknesses, mortal imperfections, frailties of the flesh and things we’re just not good at. And those can be frustrating, particularly when they appear to hinder us from achieving what we want, or even from doing what God wants us to do. But such stumbling blocks can and will be taken away, if we ‘hearken unto the Lamb of God’, through a manifestation of His words, His power and His acts.
For the time cometh, saith the Lamb of God, that I will work a great and a marvelous work among the children of men; a work which shall be everlasting, either on the one hand or on the other—either to the convincing of them unto peace and life eternal, or unto the deliverance of them to the hardness of their hearts and the blindness of their minds unto their being brought down into captivity, and also into destruction, both temporally and spiritually, according to the captivity of the devil, of which I have spoken.
Ultimately – and particularly in the present age – we are faced with two choices only. The Lamb of God’s ‘marvelous work’ will serve to sort us one way or the other. We should not be surprised if opposition to that which is good increases at the present time, even as the kingdom of God itself grows. There will be a growing divide, a sifting, and so we shouldn’t expect everyone to be convinced towards righteousness. What counts is which direction we go.
