Jesus is the only way to God
Radical corruption led man into all kinds of sinful acts including re-defining God; it's not unusual to find a person worshiping a stone or a man-made thing calling it god. This has become a normal thing among different cultures today. We also have those who indulge in self-worship; who believe every person is his own god and instead of worshiping some god they have never seen, one must worship themselves. Atheists believe in the non-existence of any god, now these seem to be the most religious as they hold a strong belief. It seems as if they have more faith than any religion on earth, because they hold a position that creation is just a matter of chance and there is no creator who created all things.
One true Religion
We have many cultures and religions who all believe in the existence of God but differ in the way they view Him, this has caused wars; many people have been killed, burned and beheaded in the name of religion, what both parties agree upon is the fact that these religions cannot co-exist and both be true, only one of them will is the true religion in the final analysis. The battle will continue until the end of the age as none will give in to defeat. One example would be the Muslims who claim to believe in the One true God; maker of heaven and earth. Their view sounds convincing on the surface but once you start reading the Quran you realize that their god is a man-made god also.
Jesus the only way
The point of tension between Christianity and all other forms religion is Jesus Christ; false religions and cults deny the Deity of Jesus Christ as well as His Messianic office. Christianity believe in Jesus Christ as The only way to God (John 14:6), the question we should ask ourselves is since these religions deny Jesus as the Son of God and the only way to God, who then gives them access to God? Their answer is simple, they say Jesus is not the only way God, in fact everyone can find his own way outside Jesus. What is false in their view is that God contradict Himself because He Says in the bible “Jesus is the only way” (John 14:6) and then to the Muslims that Muhammad is the way, it”™s obvious that to say there are other ways to God apart from Jesus is to Deny Christ and to deny Christ is to deny God.
John puts it this way “Whosoever believeth that Jesus is the Christ is born of God” (1John 5:1). God has not given us many ways or many Saviours but one Jesus Christ, there's Only One God and One Mediator between man and God The man Christ Jesus (1Tim. 2:5). “For through him we both have access by one Spirit unto the Father.” (Eph. 2:18). Jesus is the one who leads us towards the Father and without Him no man can stand before God. To say that you believe in God but don't believe in Jesus qualifies you to be a practical atheist, the Muhammedans say that Jesus was no more than human and He was just a prophet like other Old Testament Prophets including their own prophet Muhammad, they even go beyond as to deny His Death and resurrection, which are at the heart of Christianity.
It seems that we have many forms of Jesus, there's a Muslim Jesus, a Mormon Jesus, Jehovah's Witness Jesus, a Liberal Jesus and all forms of Jesus in this world but all of them are just counterfeits of the true Jesus. Since man denied the Real Biblical Jesus they went about creating their own Jesus who fits their unbelief. Jesus has been clearly set forth before all and all is without excuse; that is the reason why people worship all forms of creatures, they know that there's a God in Heaven who ought to be worshiped, so they rather change the truth of God for a lie since they have nothing to do with This God.
“But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ. For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.” 2Co 11:3-4
Legalism is another way that denies Jesus as the only access to the Father, legalists try to find their own way into the kingdom of God by their own “good deeds”, they think if they live good enough they will earn a right standing before God. But no man will be justified by the woks of the law before God but by faith in Jesus Christ (Gal 2:16). Our own good works are as filthy rags in the face of God (Isa. 64:6), God has set forth Jesus as the only way to Him and without Him no one can approach God the Father.
Jesus is the only way to God!
