We are separated from God because of Sin.  Jesus is the bridge that allows us to again have fellowship with God.  Jesus is the Way.

(John 14:6) Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.

(John 11:25) Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live

(John 11:26) And whosoever liveth and believeth in me shall never die. Believest thou this?

(1 Thessalonians 4:13) But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope.

(1 Thessalonians 4:14) For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. 

(Acts 4:8) Then Peter, filled with the Holy Ghost, said unto them, Ye rulers of the people, and elders of Israel,

(Acts 4:9) If we this day be examined of the good deed done to the impotent man, by what means he is made whole;

(Acts 4:10) Be it known unto you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even by him doth this man stand here before you whole.

(Acts 4:11) This is the stone which was set at naught of you builders, which is become the head of the corner.

(Acts 4:12) Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
