Interesting video. IMO, there are two meanings of a second coming. One literal and one Spiritual. Christ comes spiritually into every believer when we choose to believe, and we then, in that moment, that we did not know the day or hour until we made that decision, we receive the Holy Spirit. We are made Spiritually Alive, we cross over from being Spiritually dead to being made Spiritually alive. Then, I believe if God chooses to return literally at some time of His choosing He certainly can do so in the twinkling of the eye. God has a history of pouring out His wrath when humanity becomes so corrupt, unbelieving, and evil. The flood, Sodom and Gomorrah, the destruction of the temple twice etc. So a total destruction by a nuclear bomb or other means is certainly a possibility. The point is no matter what, it is wise to believe and receive Spiritual Life now, and if God pours out His wrath by whatever means your soul is saved, no matter when. 😇
