Conditions for redemption

If the earth is six thousand years old, people can be redeemed from sin.
If the earth is six billion years old, people can be redeemed from sin.

If the rapture will occur in the middle of a seven year tribulation, people can be redeemed from sin.
If the Bible doesn't really teach that there is a rapture, but, instead, that there is a triumphant procession welcoming Christ back to earth, people can be redeemed from sin.

If women can be divinely called to be ministers, people can be redeemed from sin.
If women can't be divinely called to be ministers, people can be redeemed from sin.

If . . .

But if Christ didn't come to earth as a human embryo, live a sinless life as the God-man, die a sacrificial death on the cross, and rise again, people can't be redeemed from sin.

Some things are essential. (See 1 Corinthians 15:13-21)
