God is all merciful.
I guess all those Indians not fortunate enough to have been around at and after the coming of those Europeans, simply got turned away at the Gates of Heaven.
Keep believing that if you really wish to.
God won’t be mocked. There won’t be any excuses on Judgement Day. Take it up with Him.
Jeremiah 29:13
And you will seek Me and find Me, when you search for Me with all your heart.
Matthew 7:7
“Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you.”
“God is all merciful”
Even if you flaunt your sins before Christ and refuse to repent but say you are a believer in Christ?
“Once saved always saved” is the the quote that Lucifer loves because it leads to chaos and confusion which Jesus will condemn in the end despite the audacity of it all.
God is also just. And he doesn’t owe anyone salvation.
It doesn't work that way. Because God IS merciful and wants all to be saved and come to the knowledge of the truth, He promises to be a rewarder of those who diligently seek Him. But they have to do the seeking.
