For today's persecuted Christians who are being persecuted and murdered by Muslims, Communists, Hindus and other anti-Christians - they are experiencing tribulation!
The Great Commission is not preaching "The Late Great Planet Earth".
“All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.” - Jesus speaking in Matthew 28:18-20
Sigh.
There’s a difference between tribulation that we experience living here on earth and the time of the Great Tribulation where God is bringing Israel to Himself and judging an unbelieving world.
Conflating the two makes a mess out of a lot of Scriptrue.
