I heard that he's the "Saviour of the world"

Yes,He has done so many miracles in my life including blessing me with a son after years of marriage and giving me a good job

He (Jesus) is the radiance of God's glory, the exact expression of God's nature, and he sustains all things by his powerful word. After making purification for sins, he sat down at the right hand of the majesty on high"
Jesus Christ is the Saviour of the world, he who became a sin for us so that we might be the righteousness of God through him.
He died for our sins and made himself an atonement for our sins because of the love he had for us.
This is the same Jesus, who saved me from my terrible past. I was a smoker (junky), a drunk, a drug addict, a scammer(yahoo boy), was fetish and I was into all manner of sexual immorality(masturbation, fornication, pornography addict....) I am saved from all these by his grace and the love he has for me and for the whole world.
He saved my life, my soul, and my future from destruction and he gave me hope..
If Jesus christ could save me from my sins, he's prepared to save you and forgive you all your sins too.
Why don't you give your life to christ today
Jesus christ is knocking on the door of your heart, why don't you open the door of your heart for him

Jesus is now
He loves you
He's ready to save you
1 John 1:9 if we confess our sins, he is faithful and righteous to forgive us our sins and cleanse us from all unrighteousness..
