Jesus says “I am the Son of God”. The Father says “I am God”.
This shows how far from the mark the churches and denominations are today, and that this has been sorely amis for centuries. How will there be those who will stand firm against the Beast, maybe decades from now (many from each language, people, and nation), if hardly anyone today has kept the faith? One point to bear in mind is the Revelation foretelling that an angel will preach the gospel to the whole world in the future. Maybe our children will hear and many believe. These could, by their faith in Jesus from this true gospel, be purified in Christ, and persevere through the time of the Beast and reject its 666 mark. These future faithful ones are likely all around us today, but not yet believing until they hear the gospel from the angel maybe decades from now, in time for that terrible trial of the whole world.
