“…Jesus Christ of Nazareth… Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved” (Acts 4:10,12).
A frequent objection made against Christianity is that every religion has “good” members, and to ignore them and limit heaven to a few Christians is unfair. This is a defected notion. How does one arrive at a definite conclusion when there is no one standard to gauge everyone’s “goodness?” They are “good” according to whom, according to what standard? Remember, relative morality actually does not help the sinner—he may be a “better” sinner than another, but he is also a “worse” sinner than yet another, and whether “better” or “worse,” he is still a sinner!
The God of the Bible has a simple method for determining righteousness. Today, He sees two types of people—saints and lost people. While both groups were born in sins (Ephesians 2:1-3), “shapen in iniquity [in the womb]” (Psalm 51:5), and “condemned already” (John 3:18), only the saints have come to realize their lost state. Job asked in Job 9:2, “How should a man be just [righteous, acceptable] with God?” Saints have come to the acknowledgement that they needed God’s righteousness, that they had a massive sin debt that they could never satisfy, that their “righteousnesses are as filthy rags” (Isaiah 64:6), that they could never possibly make themselves right before a holy God (He is the standard; Romans 3:23). The lost people, however, do not realize they are lost, for they believe their religious works “score points” with God and make up for their sinful deeds (2 Corinthians 4:3,4). They ignore the finished crosswork of Jesus Christ as sufficient payment for their sins (1 Corinthians 15:3,4).
Saints have come by faith to Jesus Christ, whose name literally means, “Anointed Saviour” (cf. Psalm 2:2; Matthew 1:21). As the writer of the book of Hebrews said, “[Jesus] is able also to save them to the uttermost that come unto God by him” (7:25). Literally, no world religion has such a “Saviour” as Jesus Christ! source
