God’s Method.

False teaching:
“God’s method is man”.

Their infamous excuse:
“If God’s Method is not man, how do you suppose He’s going to preach the Gospel to all people? I mean He must use “only” us right?”

An answer:
No! God can use anyone (man or not) and even Save on account of His Name as “He Wills” perfectly, it’s “His Right” to exercise “His Grace” eventually to “bring Salvation to all men” literally as this verse says (in Titus 2:11):

World English Bible
“For the grace of God has appeared, bringing salvation to all men,”

Young’s Literal Translation
“For the saving grace of God was manifested to all men,

Lastly, here’s another way (by only 1 angel) God Will use him to proclaim the Gospel to “every” tribe, tongue, people and nation before the “end” (of this age) comes as the Book of Revelation describes this:

“And I saw another angel flying in mid-heaven, having the Gospel age-during to proclaim to those dwelling upon the earth, and to every nation, and tribe, and tongue, and people,” (Revelation 14:6)

All “literally” as you can see it in plain English (no twisting of Scripture needed to prove this truth about God).

Thus, to be used by Him (in Truth) just comes as an honour to serve Him. That’s all.
