Signs of the times
"... in the last days perilous times will come: For men will be lovers of themselves, lovers of money, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, unloving, unforgiving, slanderers, without self-control, brutal, despisers of good, traitors, headstrong, haughty, lovers of pleasure rather than lovers of God, having a form of godliness but denying its power. And from such people turn away!
"...all who desire to live godly in Christ Jesus will suffer persecution. But evil men and impostors will grow worse and worse, deceiving and being deceived. But you must continue in the things which you have learned..."
2 Timothy 3:1-14
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
