And this gospel of the kingdom will be proclaimed throughout the whole world as a testimony to all nations, and then the end will come.
I suggest this is happening now but is it being done to the degree that God demands in order for this prophecy to come to pass?
And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation;
Every kindred, and tongue, and people, and nation is a lot to ask in these changing times. The bible has not been translated into every tongue considering there are over 800 languages spoken in Indonesia alone. Then again it does not say the bible has to be translated into all those tongues just that the gospel is spoken there.
In this computer age there is translation software for a great deal of languages. If there is a market for it someone will try and make money from it. The United States is a buyers market, many nations want to learn English just to make money. If there is translation software we have no idea how many of those peoples have visited the gospel in a language they have been studying.
In this computer age there are thousands of webpages presenting both sound doctrine and false doctrine. We can only leave access up to God.
God is faithful and the Father will not leave one of His children behind.
According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
We can come to Him now by faith. In any loving relationship it is important to enjoy it now rather than waiting for being called home. Relationships take time and effort.
