In this case, the problem can be hooked on both the secular and the spiritual side.
The question of whether Jesus really existed and was a historical figure who actually carried out his teaching activity in Jerusalem has already been answered in one of the previous parts of the article. But for believers, for all Christians, Jesus is more than just a man who gave his advice and teachings at the beginning of our century. Jesus Christ is one of the 3 people who together form the Holy Trinity (God the Father, the Son of God and the Holy Spirit). He is above all the Son of God who was sent by his Father to Earth on a great mission.
The mission by which human sins were to be redeemed. And His coming again before the final judgment is promised. People of deep faith have no doubt about the existence of the Lord Jesus. He is the unquestionable and central essence of our faith. He is the pillar on which this faith was built. He is the one who tells us how we should be guided in our lives, and He is the only mediator between us and God. He has repeatedly proved the power of his role through his revelations (about which you will also find information in this previous chapter of the article).
Considering all these facts and combining them with the undeniability of Jesus' historical presence in the world, we can say with certainty that Jesus really existed.
