It was Jesus who began teaching that if you do not have the Son of God-if you do not know Him intimately through saving faith in Him-then you do not have life and will not enter Heaven. Believe what you will in regards to Christian teachings, but this is the word our Lord passed down to us. We should go forth not boasting but pleading with the lost to know Christ in the way we do. One needn’t enter the church to come to Christ. In fact it is only by being born again through personal faith in the Savior that one becomes a part of the church and a child of God, Acts 2:47; Galatians 3:26. The Christian outlook should be more along the lines of “we want you in, too!”
We do indeed zealously and dogmatically defend “Christ alone” for salvation. Our Lord championed it; the Bible is rife with this teaching; it only makes sense that Heaven’s Creator is the only one suited for explaining how one reaches this coveted destination. It is not arrogance, pride, vanity or naiveté that compels a Christian to make this stand. When one finds the truth about a matter should we be ashamed to proclaim it? If Christianity can be debunked and disproven then the hope of the church is lost. If Christ never rose then our faith is futile, 1st Corinthians 15:17.
However, if Christianity is true then it will not and cannot suffer rivals. Rival suitors for one’s soul are automatically found to be false and deceptive. How many truths does one need about eternity? Who would you feel more secure about getting directions from: spiritual and religious leaders who have all died, or the Son of God who conquered death; who came from Heaven for that very purpose?
