Jesus Christ is the Son of God. He is part of the Holy Trinity and has been there since the beginning. He is not a created being, but the creator. Through Him all things were created.
For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him
COLOSSIANS 1:16 (KJV, HOLY BIBLE)
As God is Holy and required a perfect sacrifice to permanently restore a relationship with mankind, Jesus became human and died for our sins. He was blameless, yet carried the sins of the world (all generations past and future) on his shoulders. He bore our curse and was forsaken by God, so that everyone who accepts Him as the Son of God and their Saviour, can be saved from damnation and eternal death. He was crucified, but raised from the dead and ascended to His Father (God), in heaven.
Through Christ, we get to be adopted into God’s kingdom as God’s children. Not only did He save us, He extended an invitation to every human to be part of His family, eternally. There never was nor ever will be a greater love.
Jesus Himself revealed everything in the Book of Revelation to John, who wrote it down. This is the only book in the Bible that carries a special blessing to the reader/hearer, if they believe and respect what it says. This book contains a detailed description of what to expect in the coming days. Jesus will be coming back to earth to reign as king. He will save Israel and restore them to the glory promised in the Old Testament, once they realize that He truly was their Messiah and call on Him to return.
