Jesus will reign forever

That is to say,Jesus Christ is our Eternal Lord and God and Saviour.His essence,Power and Authority remain the same even before the beginning of all things,both those in Heaven and on earth and beneath the earth or the sea.Though all things shall pass but He is Everlasting God. He is known as the Mighty God and Everlasting Father(Isaiah 9:6),meaning He ever existed and created all things in His power (John 1:1-3, Colossians 1:16). He is the Sustainer of all things (Colossians 1:17),without Him nothing will exist ,including dark spirits. He is the Saviour of the world(Redeemer). He is the only Loving God who laid His life down to save all men from the death penalty of their sins when everybody had gone astray(Isaiah 53:4-6)-Behold,the Lamb of God Who takes away the sin of the world! (John 1:29). He is the Supreme Judge for all humans(Matthew 25:31-46),and the Sovereign Lord Who is to come and reward the good deeds of men,and punish men for their wickedness(Revelation 22:12-13).

This scripture is saying that Jesus Chris is God, that the good works He had done in the past are still on and will continue till we meet face to face with Him

I believe in other words Jesus is indeed God & this
is the certain sure that He was God, for only God was since the beginning

Jesus is God, remains the same. He was there showing great works, today he is able too and in the time to come . He will not repent on his word.
