People would not believe, if they didn't see. God sent his son(Jesus) to the Earth, to die, so our sins would be forgiven. People saw this and believed.
The Bible, God's Word, gives us many reasons as to why Jesus came to this earth:
"Even as the Son of man came not to be ministered unto (served), but to minister, and to give his life a ransom for many." Matt. 20:28; Mk. 10:45
"For the Son of man is not come to destroy men's lives, but to save them." Luke 9:56
"I am come to send fire on the earth..." Luke 12:49
"For the Son of man is come to seek and to save that which was lost." Luke 19:10; Matt. 18:11
"The thief comes not, but for to steal, and to kill, and to destroy:
I am come that they might have life, and that they might have it more abundantly." John 10:10
"Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God." Heb 10:7
"For I came down from heaven, not to do my own will, but the will of him that sent me. And this is the Father's will who has sent me, that of all which he has given me I should lose nothing, but should raise it up again at the last day. And this is the will of him that sent me, that every one who sees the Son, and believes on him, may have everlasting life: and I will raise him up at the last day." John 6:38-40
"And you know that he was manifested to take away our sins; and in him is no sin..... For this purpose the Son of God was manifested, that he might destroy the works of the devil." I John 3:5,8
"In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him. Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation (the atoning sacrifice which reconciled us to The Father) for our sins." 1 John 4:9,10
"I came not to call the righteous, but sinners to repentance." Luke 5:32; Matt. 9:13; Mk. 2:17
"Now is my soul troubled; and what shall I say? Father, save me from this hour: but for this cause came I unto this hour." John 12:27
He came to die for our sins!
"I am come a light into the world, that whosoever believes on me should not abide in darkness.... for I came not to judge the world, but to save the world." John 12:46,47
".... To this end was I born, and for this cause came I into the world, that I should bear witness unto the truth..." John 18:37
"This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners..." I Tim 1:15
"Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil." Matt. 5:17
".... I am not come of myself, but he that sent me is true....." John 7:28
"And Jesus said, For judgment I am come into this world, that they which see not might see; and that they which see might be made blind." John 9:39
"Wherefore when he comes into the world, he said, Sacrifice and offering you would not, but a body have you prepared me: In burnt offerings and sacrifices for sin you have had no pleasure. Then said I, Lo, I come (in the volume of the book it is written of me,) to do your will, O God." Heb 10:5-7; Ps. 40:6-8
"For then must he often have suffered since the foundation of the world: but now once in the end of the world has he appeared to put away sin by the sacrifice of himself." Heb 9:26 "The Spirit of the Lord is upon me, because he has anointed me to preach the gospel to the poor; he has sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised, To preach the acceptable year of the Lord." Luke 4:18,19
[size=+1]JESUS SENT BY THE FATHER
FOR THE SALVATION OF THE WORLD[/size]
1. Christ reveals himself throughout his earthly life as the Saviour sent by the Father for the salvation of the world. His very name, "Jesus", expresses this mission. It actually means: "God saves".
It is a name he was given as a result of heavenly instruction: both Mary and Joseph (Lk 1:31; Mt 1:21) receive the order to call him by this name. In the message to Joseph the meaning of the name is explained: "for he will save his people from their sins".
2. Christ defines his saving mission as a service whose highest expression will be the sacrifice of his life for mankind: "For the Son of man also came not to be served but to serve, and to give his life as a ransom for many" (Mk 10:45; Mt 20:28). These words, spoken to counter the disciples tendency to seek the first place in the kingdom, are primarily meant to awaken in them a new mentality, which conforms more closely to that of the Teacher.
In the Book of Daniel, the figure described as "one like a son of man" is shown surrounded by the glory due to leaders who receive universal veneration: "all peoples, nations, and languages should serve him" (Dn 7:14). Jesus contrasts this figure with the Son of man who puts himself at the service of all. As a divine person, he would be fully entitled to be served. But in saying he had "come to serve", he shows a disturbing aspect of Gods behaviour: although he has the right and the power to make himself served, he puts himself "at the service" of his creatures.
Jesus is the only Saviour and MediatorJesus expresses this desire to serve in an eloquent and moving way at the Last Supper when he washes his disciples feet: a symbolic act which will be impressed as a rule of life on their memory for ever: "You also ought to wash one anothers feet" (Jn 13:14).
3. In saying that the Son of man came to give his life as a ransom for many, Jesus is referring to the prophecy of the suffering Servant who "makes himself an offering for sin" (Is 53:10). It is a personal sacrifice, very different from the animal sacrifices used ancient worship. It is a life given "as a ransom for many", that is, for the immense multitude of humanity, for "all".
Jesus thus appears as the universal Saviour: all human beings, according to the divine plan, are ransomed, freed and saved by him. Paul says: "Since all have sinned and fall short of the glory of God, they arejustified by his grace as a gift, through the redemption which is in Christ Jesus" (Rom 3:24). Salvation is a gift that can be received by each one to the extent of his free consent and voluntary co-operation.
4. As universal Saviour, Christ is the only Saviour. Peter affirms this clearly: "There is salvation in no one else, for there is no other name under heaven given among men by which we must be saved" (Acts 4:12).
At the same time, he is also proclaimed the only mediator between God and men, as the First Letter to Timothy affirms: "For there is one God, and there is one mediator between God and men, the man Christ Jesus, who gave himself as a ransom for all" (1 Tm 2: 56). As the God-man, Jesus is the perfect mediator who unites men with God, obtaining for them the goods of salvation and divine life. This is a unique mediation which excludes any competing or parallel mediation, although it is compatible with participated forms of mediation (cf. Redemptoris inissio, n. 5). Consequently, any other autonomous sources or ways of salvation cannot be admitted apart from Christ. Thus in the great religions, which the Church considers with respect and esteem in the way indicated by the Second Vatican Council, Christians recognize the presence of saving elements, which nevertheless operate in dependence on the influence of Christs grace.
Therefore these religions can contribute, by virtue of the mysterious action of the Holy Spirit who "blows where he wills" (Jn 3:8), to helping men on their way to eternal happiness, but this role is also the fruit of Christs redemptive activity. Thus with regard to other religions, Christ the Saviour is also mysteriously at work. In this task he unites to himself the Church, which is in a way the "sacrament of communion with God and of unity among all men" (Lumen gentium, n. 1).Christ alone can satisfy all our desires
5. I would like to conclude with a wonderful passage from the Treatise on True Devotion to the Blessed Virgin, by St Louis de Montfort, which proclaims the Christological faith of the Church: "Jesus Christ is the Alpha and the Omega, the beginning and the end of everything.... He is the only teacher from whom we must learn; the only Lord on whom we should depend; the only Head to whom we should be united and the only model that we should imitate. He is the only Physician that can heal us; the only Shepherd that can feed us; the only Way that can lead us; the only Truth that we can believe; the only Life that can animate us. He alone is everything to us and he alone can satisfy all our desires.... Each one of the faithful who is not united to him is like a branch broken from the stem of the vine. It falls and withers and is fit only to be burnt. If we live in Jesus and Jesus lives in us, we need not fear damnation. Neither angels in heaven nor men on earth, nor devils in hell, no creature whatever can harm us, for no creature can separate us from the love of God which is in Christ Jesus.
Through him, with him and in him we can do all things and render all honour and glory to the Father in the unity of the Holy Spirit; we can become perfect and be for our neighbour a fragrance of eternal life" (n. 6 1).
