When there are so many religions in the world, how can Christianity claim to be the only way to God?

Most religions say Jesus was a great teacher or prophet. So focus on that great teacher. Until you do, God will remain a blur. Suppose I was off-colour and two eminent doctors examined me. Dr A's diagnosis was that I had a life-threatening illness, but treatment X would cure me. Dr B said it was only a cold and treatment Y would cure me. Dr A's more drastic diagnosis doesn't in itself mean he is right, but it means I'd be a fool not to give higher priority to checking out his claims. Consider a worst-case scenario. Suppose another religion were right and instead of following that religion, I became a Christian. Many religions would say the Christian life is reasonably moral. So, according to them, although I would miss top spot, my life after death would be fairly comfortable. A few claim that if I ignored their religion, after death I'll cease to exist. I can handle that. Some say I'd get another chance through reincarnation. That's not too bad. But, relative to almost all religions, Jesus increased the stakes enormously. If he is right and I ignore him, the consequences are unthinkable. This man, renowned for his love, humility and honesty, warned that only by committing myself to him can I avoid an eternity of torment in hell. (Matthew 20:28, 25:32-34,41,46; John 3:16; 14:6) In addition, unlike most other religions, Jesus leaves his believers certain that they will enter heaven. Other religions typically place so many requirements on their adherents before they could be considered worthy of heaven that their followers endure a lifetime of uncertainty as to whether they have met those requirements. You're gambling with eternity. Jesus alone is the sinless Son of God who suffered an agonising death so that you and I could escape eternal torment and enjoy heaven. Improve your odds on life's most serious gamble by giving priority to weighing Jesus' claims. To determine if Jesus' teaching is from God requires divine insight. Whether God grants a person this spiritual understanding hinges on a single factor. That critical factor, said Jesus, is your willingness to obey God. (John 7:17) Why should God bother to open your eyes to spiritual truth if you are unwilling to respond to that truth? Yet few of us are prepared to pay that price. It involves a willingness to relinquish our hopes and dreams for the future, to forego our pet sins and anything else God may ask. Such abandonment seems crazy until we consider who God is. The God who made and sustains the entire universe is the source of all knowledge, moral goodness and love. That means he is good, he is trustworthy, he has our best interest at heart, he is wiser than us and he loves us more than we love ourselves. Obeying God is the smartest thing anyone could ever do. Until we acknowledge this and are willing to obey God, we obviously don't want God in our lives. (We might want him as our slave, or as a curiosity, but not as God.) If so, why should God waste time giving us the spiritual discernment to know whether Jesus is the only way to God? Until we rectify this we can expect God to let us remain spiritually confused, subject to the deceptive powers of anti-God influences, unable to determine which religion is right. What does it matter whether it’s Jesus you worship, or some other religion?

It’s all religion. That’s equivalent to asking a wife, deeply in love with her husband, ‘What does it matter if it’s you that your husband has sex with, or a prostitute? It’s all sex.’ That’s the very analogy Scripture employs over and over, using such expressions as ‘playing the harlot’ for mixing true worship with another religion. To make the analogy even closer, involvement with another religion is like prostituting yourself to a carrier of the lethal AIDS virus.
