You have my best wishes for your future. Having said, and meant, that, one does hope you will at least learn to avoid your persistent name-calling at some point. I shall pray for that, if it is not too "arrogant" of me to do so.
What logic? The author said “We can however, know very closely when Jesus will return so that the exact day is not a surprise. “. That is counter to scripture as stated in Mark.
“No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father” (Mark 13:32). Seems pretty clear to me.
“for you know very well that the day of the Lord will come like a thief in the night. While people are saying, “Peace and safety,” destruction will come on them suddenly, as labor pains on a pregnant woman, and they will not escape. But you, brothers, are not in darkness so that this day should surprise you like a thief.” (Thessalonians 5:2-4)
The Thessalonians passage tells us Jesus will come like a thief in the night. No one can predict when a thief strikes. This last sentence doesn’t mean man should be able to predict when the steps preceding Christ’s return will occur (as Mark states that is impossible for even Jesus Christ Himself) but rather when the “Day of the Lord” actually occurs - Christ’s return - we won’t be surprised.
Be prepared at any time - that’s the message. No need for the rest of the nonsense in this article purporting to play God and predict the future. Countless fools have claimed to do that in the past and they were all wrong. God’s Word is enough for me.
