Concern over temporary realities is legitimate and noble to a point. It's just not primary. The only vehicle I know for accessing that which is timeless is faith. The five senses are not much help. Television is about as time bound as you can get.
Celebrity is all the rage today, but it's about as timeless as a hairstyle.
No way, not even great nations are timeless. A better place to search for things timeless is a children's Sunday School class. Sure, even toddlers will soon be using canes. However, what is timeless is what they are being taught. I admit these fruits are not timelessly consistent in me but the Spirit who gives them is timeless.
