Waiting is going to play an important part in end times.
All through the Bible, God entreats us to wait upon Him.
During the end times, we need to wait with anticipation of our coming Lord and not become weary. (Hebrews 12:3 NASB)
Many, however, will become disillusioned and tired of waiting for the return of Jesus (the rapture) and will fall away from the faith in the end-time rebellion, called the apostasy.
(read: 1 Timothy 4:1, 2 Thessalonians 2:3)
We must not give up but trust God ...
and to wait for His Son from heaven, whom He raised from the dead, that is Jesus, who rescues us from the wrath to come.
--- 1 Thessalonians 1:10
Waiting upon the Lord will be one of many events to test our faith in the Lord during the end times. Do not think it is strange.
Waiting takes great faith.
Waiting upon the Lord strengthens:
our faith,
our endurance,
and our perseverance.
