John 21:23 KJV — Then went this saying abroad among the brethren, that that disciple should not die: yet Jesus said not unto him, He shall not die; but, If I will that he tarry till I come, what is that to thee?
And the specifics of what Jesus has said matter.
Every word, every syllable, every inflection.
Because if He said it, then not one word of His will fail to come to pass.
Your part is to simply fellowship with the Lord. And whatever He says to you, do it.
