This is an amazing description on knowing that we can know the time we are in regarding Matthew 24.
This is a long read that is worth it!
Amos 3:7 Surely the Lord God will do nothing, unless He revealeth His secret unto His servants the prophets.
The above verse is a simple and broad declaration. If you accept it literally, the case is made that the Sovereign Lord's servants the prophets will know even the times and dates of his coming. To suggest that any subset of knowledge about what the Lord will do will be kept secret from the prophets is to contradict the scripture. But that's not a very persuasive argument for some of you, so let's continue. Consider the following verse.
Luke 8:17 For there is nothing hidden that will not be disclosed, and nothing concealed that will not be known or brought out into the open.
