John 14:3

3. Go and prepare a place Through his death he would open a new and living way (Hebrews 10:20) into the heaven which his merit had purchased.

I will come again According to the law of prophetic perspective, to which we have so often referred, the Second Advent of our Lord is beheld with clear distinctness in the near distance. For this reason we reject here, as elsewhere, all reference of the coming of the Son of man to the period of death. Nor does the Saviour here refer, as many commentators imagine, to a general spiritual coming, extending along the entire interval to the end of time. The day in which Christ shall come again to take believers home is the day of judgment described in Matthew 24:25.

Unto myself… where I am… ye… also Emphatically does our Lord in these terms indicate that the happiness of heaven, both of Christ and his redeemed, will consist in their reunion in love.
