A true believer, does not need a 1960's computer or biblical calculations from someone, who with good intentions, sought to urgently demonstrate the almost complete day and the missing 40 minutes in time, in the days of Joshua and Hezekiah respectively; anyway, even if they confirmed these historical events in a scientific way, he who does not want to believe in God, will never do it! The very "father" of atheism was a Jesuit, and if a biblical scholar ended up this way, what shall we say of those who have not touched this precious and wise book?
Those who have truly had a personal encounter with the Most High God, have as undoubted proofs of His power, the intimate contemplation of His beauty and holiness, as well as the manifestations of His power and blessings in their own lives.
What some science fiction authors and scientists talked about regarding a supposed "parallel world", relativity or incredible "time machines", was only their absurd opposition to the only one capable of having foreknowledge of the events, and their possible influence on them; this is God.
The Creator subjected the world and the universe under a context of space, time, physical and chemical laws, being impossible to avoid it; except when we die or when we receive on the final day, what our works deserve. Man cannot go beyond the limits established by God.
Daniel 2:20-22 NKJV
20 Daniel answered and said:
“Blessed be the name of God forever and ever,
For wisdom and might are His.
21 And He changes the times and the seasons;
He removes kings and raises up kings;
He gives wisdom to the wise
And knowledge to those who have understanding.
22 He reveals deep and secret things;
He knows what is in the darkness,
And light dwells with Him.
Isaiah 40:21-23 NKJV
21 Have you not known?
Have you not heard?
Has it not been told you from the beginning?
Have you not understood from the foundations of the earth?
22 It is He who sits above the circle of the earth,
And its inhabitants are like grasshoppers,
Who stretches out the heavens like a curtain,
And spreads them out like a tent to dwell in.
23 He brings the princes to nothing;
He makes the judges of the earth useless.
Deuteronomy 29:29 NKJV
29 “The secret things belong to the Lord our God, but those things which are revealed belong to us and to our children forever, that we may do all the words of this law.
