I am Alpha and Omega, the beginning and the end, the first and the last. Rev 22:13 Jesus tells us again that He is Lord.

★ Alpha and Omega - what He says
★ beginning and the end - what He does
★ first and the last - who He is

Lord is the term the Hebrews used instead of speaking YHVH the name they assigned to the Creator, the breath of life.   

The Hebews used other names to describe the functions that the Creator performed or His characteristics.   

All the names of deity that occur in scripture were attempts at understanding our Creator.   

Jesus says unto him, I am the way, the truth, and the life: no man comes unto the Holy Spirit Father, but by me. Joh 14:6 Jesus introduces the sandwich prayer - praise, petition, praise.      Isn't it interesting that Christians have been praying this prayer for 2000 years and yet most Christians do not know the name of the Holy Spirit Father?      Oh yes, some Christians will give you a litany of names from the Old Testament, especially YHVH, but still refer to Him as God (which is just a title) or Father which is just a role.      When Jesus spoke these words to His disciples He was leading them to a monumental Truth.     They were still trying to understand who this man was.     So, He could not have held on to them if He told them that the name of the Father was Jesus and that the Father was standing before them and speaking to them.      So, Jesus instructs them to pray to the Father and hallow His 'name' without telling them the Father's name.     The disciples like Christians today either assumed the 'name' to be YHWH or Lord or God.      It was only at the end of His ministry, before going to the cross, that Jesus told them who He is, who the Father is and what the Father's name is Joh 14:6-14 though He had laid down many hints.     Joh 1:18 Joh 5:37 Joh 10:30.      We are to refer to the Holy Spirit Father of Christ Jesus using His name which is Jesus.     We are to ask the Holy Spirit Father for what we need using the name of Jesus Joh 14:13 Joh 15:16 Joh 16:23.

Jesus is the Truth about our Creator.   He came to settle the issues and questions surrounding the concept of `God`.   

Those who would seek `God` must find Him In Christ Jesus.   This is what Jesus meant when He talked about the Strait Gate and the Narrow Way.   

The Gospel is the good news that `God` is not just our Creator but that He is also our Saviour, our Healer, our Deliverer, our Hope and our very Life.   

The Gospel is the revelation of `God` In Christ Jesus, that Jesus Is Lord.
