For Inclusivism
1) Old Testament saints are not Christians but believers in God. They could not put trust in Jesus because He did not exist in human form.
2) Nobody comes to God without the work of the Holy Spirit. The Spirit is at work convicting people of sin and seeking to turn their sinful hearts toward God. Whether people have creational or biblical revelation, it is the same Spirit who guides them to God, either through knowledge of the historical Jesus or through creation and providence (pg. 43).
3) The unevangelized are sinners who have turned away from God. It is sinners that the Holy Spirit desires to turn around – beginning with repentance.
4) Not all unevangelized people are saved. Some unevangelized are believers in God, while others are not. Some unbelieving unevangelized reject the gospel when it is made know to them.
Against Inclusivism
1) General revelation makes people aware of the presence of God but does not save them.
2) Inclusivism creates a salvation apart from trusting in Jesus as savior. Jesus is the basis for salvation.
3) With Inclusivism, revelation can be any “light” accredited to God. There is no definitive understanding of the nature of that light but only that it requires “faith” towards God. Any amount of faith will secure salvation even in profound ignorance.
4) Inclusivism does not consider imago dei and the historical unity of the human race back to Adam. While it does not promote universalism per se, it does suggest that God accepts everyone and only those who reject the work of the Spirit (through whatever form of revelation they are influenced by) are considered lost.
