I came from the Father and entered the world.  Now I am leaving the world and going back to the Father.  John 16:28

Behold, I am returning soon.  My reward is with me and I will give to you according to what you have done.  I am the Alpha and the Omega, the First and the Last, the Beginning and the End.  I am the root and the offspring of David and the bright Morning Star.  Rev 22:12-13,16 

I am the Living One.  I was dead but now I am alive forever and I hold the keys of death and hell.  Rev 1:18

I rebuke and discipline those I love so be zealous and repent.  Here I am - I stand at the door and knock.  If you hear my voice and open the door, I will come in and eat with you and you with me.  I will give you the right to sit with me on my throne just as I overcame and sat down with my Father on his throne.  Rev 3:19-21

What I open no one can shut and what I shut no one can open.  Rev 3:7

Stop doubting and believe.  John 20:27

Do not let your heart be troubled.  Trust in God, trust also in me.  In my Father's house there are many mansions.  If it were not so, I would tell you.  I am going there to prepare a place for you and if I go and create a place for you, I will come back and take you to be with me so that you also may be where I am.  You know the way to the place where I am going.  John 14:1-4

I am the way, I am the truth and I am the life.  No one comes to the Father except through me.  John 14:6

Come to me - you who are weary and burdened and I will give you rest.  Take my yoke upon you and learn from me.  I am gentle and humble in heart and you will find rest for your soul.  My yoke is easy and my burden is light.  Matt 11:28-30

Peace I leave with you.  My peace I give you.  I do not give to you as the world gives.  Do not let your heart be troubled and do not be afraid.  John 14:27

And surely, I am with you always to the very end of the world.  Matt 28:20
