Truths we have been learning for years will have to be learned in a few months by others

It is too late in the day to feed with milk....Truths that we have been years learning, must be learned in a few months by those who now embrace the third angel's message.  We had to search and wait the opening of truth, receiving a ray of light here and ray there, laboring an pleading for God to reveal truth to us.  But now the truth is plain; its rays are brought together....It is a disgrace for those who have been in truth for years to talk of feeding souls who have been months in the truth, upon milk....Those who embrace the truth now will have to step fast.  Ellen G. White, Time is Short
