In the Epistle of Barnabas, it says
Barnabas 15:3 Of the Sabbath He speaketh in the beginning of the creation; And God made the works of His hands in six days, and He ended on the seventh day, and rested on it, and He hallowed it.
Barnabas 15:4 Give heed, children, what this meaneth; He ended in six days. He meaneth this, that in six thousand years the Lord shall bring all things to an end; for the day with Him signifyeth a thousand years; and this He himself beareth me witness, saying; Behold, the day of the Lord shall be as a thousand years. Therefore, children, in six days, that is in six thousand years, everything shall come to an end.
Barnabas 15:5 And He rested on the seventh day. this He meaneth; when His Son shall come, and shall abolish the time of the Lawless One, and shall judge the ungodly, and shall change the sun and the moon and the stars, then shall he truly rest on the seventh day.
And we know that the World (Human History) according to Bible is now almost 6000 years. This means The Second Coming of Jesus will happen within 50 years from now.
According to Saint Malachy Prophecy we can know that it has the same timeline.
How should we interpret these things?
