Salvation Found Only in Christ
And 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
To the post-modern mind, no one religion can claim to have all the truth. No one way can be the only hope of salvation. No one person can claim to be the sole means to living life in all its fullness. Post-moderns assert that those individuals who make such an exclusive claim are intolerant and arrogant.
Yet much to their dismay, Jesus makes that very claim: He is the exclusive Savior of the world, the only means to salvation, and the only one who can bring true fulfillment (John 14:6).
To claim that Jesus Christ is unique is not to say that there is no truth in other religions and ideologies. Of course there is. For we believe in God’s general revelation and common grace. The Logos of God is still ‘the true light’ coming into the world and enlightening every man (Jn. 1:9). All men know something of God’s glory from creation and something of God’s law from their own nature, as Paul argues in Romans 1 and 2.
But how does this argument continue? Not that their knowledge of God saves them, but the very opposite! It condemns them because they suppress it. Indeed, ‘they are without excuse, for although they knew God they did not honour him as God  . . . .” It is against this dark background of the universal rebellion, guilt and judgment of mankind that the good news of Jesus Christ shines with such dazzling beauty.
There is salvation in no other, for there is no other mediator between God and man but only Jesus Christ who died as a ransom for sinners (Acts 4:12; 1 Tim. 2:5-6). Firmly to reject all syncretism in this way and to assert the uniqueness and finality of Jesus Christ is not ‘doctrinal superiority’ or imperialism, as it has been called. Conviction about revealed truth is not arrogance. Its proper name is ‘stewardship’, the humble and obedient stewardship of a church which knows it has been ‘put in trust with the Gospel’.
