Knowing this first: that scoffers will come in the last days, walking according to their own lusts, and saying, “Where is the promise of His coming? For since the fathers fell asleep, all things continue as they were from the beginning of creation.” 2 Peter 3:3-4
'He was' and 'He is' each have their problems for those who will not believe in the Christ. But if the past tense is easier and the present one more difficult, then the third separates the faithful from the fallen with the sword of the Word. Many in this world would rather continue on as before until somehow fallen humans achieve some sort of utopian-ageless-evolved paradise on Earth. (You may estimate for yourself how well we are doing on that!) The Revelation 1:7 tells of tribes mourning when Jesus returns (also Matt 24:30). Perhaps that will happen just after they think aging has been stopped. As for me, I think I have aged one day for each day I've been alive. (I guess that makes sense.) What the promise of our Lord's return grants to those who believe in Him is, well, the promise of His return! Like the aging thing, it just sort of makes sense to us. Since I cannot point to the hour, day, month, and year of His return, and neither can anyone else, many refuse to believe this appointment will ever arrive. And so they scoff, and may be scoffing at the moment of our Lord's return.
Pray for those who refuse to believe, while there is still time for repentance,
