Mathew 24 vs 27-30 clearly states some signs about the second coming of Jesus Christ.
1. Jesus Christ is not going to come secretly unannounced in a secret place.
2. There will be tribulations but these are just to herald the second coming of Jesus Christ.
3. The following will happen just before the second appearance of Jesus:
• Total eclipse of the sun-The sun shall be darkened
• Total eclipse of the moon- The moon shall not give light
• Stars shall fall from heaven
• Powers in the heaven shall be shaken- evil powers shall fail
• Glory of the Lord shall appear in the sky and heavens
• Jesus shall appear in the clouds in great glory and power
• A trumpet shall be blown.
• Angels shall gather the elect in heaven and earth
