Signs of the times
"...in latter times some will depart from the faith, giving heed to deceiving spirits and doctrines of demons."
1 Timothy 4:1
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
