"But the life of John was not spent in idleness, in ascetic gloom, or in selfish isolation. From time to time he went forth to mingle with men, and he was ever an interested observer of what was passing in the world. From his quiet retreat he watched the unfolding of events. With vision illuminated by the Divine Spirit, he studied the characters of men, that he might understand how to reach their hearts with the message of heaven. 8T 221.2"
"In those days came John the Baptist, preaching in the wilderness of Judea,"
Both passages refer to John's ministry. Matthew 3:1 introduces John's preaching, while EGW elaborates on his character and preparation for that ministry.

Both passages discuss John's time in the wilderness. Luke 1:80 mentions his presence there, while EGW expands on the nature of his life and observations during that period.
