Church Fathers on John 14:19

That no one might think, because our Lord was about to give the Holy Spirit, that He would therefore not be present Himself in Him, He adds, I will not leave you comfortless. The Greek word signifies “wards.” Although then the Son of God has made us the adopted sons of the Father, yet here He Himself shows the affection of a Father towards us.

At the first He said, Where I go you shall come; but as this was a long time off, He promises them the Spirit in the interval. And as they knew not what that was, He promises them that they most desired, His own presence, I will come to you, but intimates at the same time that they are not to look for the same kind of presence over again: Yet a little while, and the world sees Me no more: as if He said, I will come to you, but not to live with you every day as I did before.…

As if He said, Though I shall die, I shall rise again. And you shall live also, i.e. when you see Me risen again, you will rejoice, and be as dead men brought to life again.
