Contradiction with Matthew 24:36
This verse states that no one knows the day or hour of the end, not even the angels in heaven or the Son, which contrasts with Mark 13:23 where forewarnings are given.
Matthew 24:36: But of that day and hour knoweth no [man], no, not the angels of heaven, but my Father only.
Contradiction with Acts 1:7
This verse suggests that times and dates are set by the Father's authority and are not for us to know, conflicting with the idea in Mark 13:23 of being forewarned.
Acts 1:7: And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.
Contradiction with 1 Thessalonians 5:2
This verse implies that the Lord's coming will be like a thief in the night, unforeseen, while Mark 13:23 suggests awareness of the signs beforehand.
1 Thessalonians 5:2: For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
Contradiction with 2 Peter 3:10
This verse declares that the day of the Lord will come as unexpectedly as a thief, counter to the idea of being forewarned in Mark 13:23.
2 Peter 3:10: But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
