Signs of the times
"Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching. For the time will come when they will not endure sound doctrine, but according to their own desires, because they have itching ears, they will heap up for themselves teachers; and they will turn their ears away from the truth, and be turned aside to fables. But you be watchful in all things..." 2 Timothy 4:2-5
"Thus says the Lord: 'Stand in the ways and see,
And ask for the old paths, where the good way is, and walk in it;
Then you will find rest for your souls.
But they said, ‘We will not walk in it.’"
Jeremiah 6:16
To prepare His people for future events, Jesus told His disciples,
"Now learn this parable from the fig tree: When its branch has already become tender and puts forth leaves, you know that summer is near. So you also, when you see all these things, know that it is near... Watch therefore...." Matthew 24:32-33, 42
