We recently began attending a church about 30 miles away. Been there three times and didn't go this last Sabbath.
Each and every week, since we FIRST walked through their doors, including the week we "missed", we've gotten a brief phone call from one of the elders / deacons (not sure precisely which), asking how we're doing, how the kids (who haven't gone) are doing, if we need anything, how can they help, let 'em know if we do. That is overwhelming (good) and 100% unprecedented in my 49 years of experience in a lot of churches. Something to think on.
As to relevance of the Gospel ... Yes, Tlaloc, the Gospel is ALWAYS relevant, completely. The methods of presentation can use modification from time to time. Ex: "... they shall be white as snow." Snow? If I live in Haiti, how'm I gonna relate to that?
I'm reminded of the story about a missionary to a tribe in New Guinea who was getting nowhere at all until he told how Jesus spit on the ground and made mud and put it on a man's eyes and healed him. All of a sudden the tribe connected, "Oh! Jesus was a spitter! And a great one." It cracked the door for them as their healers did much the same, using muds made with spit.
A member of modern society, say a lifelong resident of The Big Apple, may intellectually understand the agrarian models Jesus used in parables to a point, but not really connect with them, having no similar experiences with agrarian life. The sower went forth to sow...? But give him a story about a diversified portfolio, some of which produced and some of which were duds, and how the portfolio managed / kept / discarded, etc. and he might well connect on that deep "I get it" level.
