Jesus Will Return For His Church

Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven.
Acts 1:11

 Even as the testimony of Christ was confirmed in you:  So that ye come behind in no gift; waiting for the coming of our Lord Jesus Christ:  Who shall also confirm you unto the end, that ye may be blameless in the day of our Lord Jesus Christ.
I Corinthians 1:6-8

John 14
 1 Let not your heart be troubled: ye believe in God, believe also in me.
 2 In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.
 3 And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.
