19 After a little while the world will no longer see Me, but you will see Me; because I live, you will live also. John 14:19 (NASB)
When our Lord spoke of the “world” in John 14:19, He was talking about those in this temporal existence who are not in Him. They are not true Christians even though some in that group may profess to be so. In this context He was also referring to the Jewish religious leaders of His own day who so opposed Him and His ministry and who would continue to oppose the early church as is seen all through the book of Acts for example. What is it that separates those alive in Christ in this world from those who are not? Those in Christ are the ones who truly see Jesus for who He really is, believe and are saved from those who refuse to do so, reject the gospel, and remain in their sins, even if they may develop a form of Christianity that suits them, but is absent of the real Jesus.
