This sounds like a very large question. Far too much for a short article like this one would say. On the other hand, one might say the message of the Gospel is, and has always been, very simple.
Love God with all your heart and soul, love your neighbor as yourself. Jesus fleshes it out at the end of Matthew 25 in the “Great Judgment”.
You know the words… I was hungry, you fed me … I was thirsty, you gave me drink … I was a stranger, you welcomed me, and so on.
You get the idea, these are NOT impossible expectations! These are “being a decent human being” things that anyone can do. These are also the things in which the church needs to take the leading role, now and in the future!
