Enoch walked FAITHFULLY with God. I think faithfully was the key thing that Enoch did to please God. I believe for us to be pleasing to God we can’t just follow Him when we feel like it. When we become Christians we commit to following Christ and I know for myself that if I am not faithfully reading His word or praying that I feel a distance between God and myself. I don’t think God expects us to be perfect in following Him but that when we realize that we are falling away, we get back on track again. Unlike all the other people it talks about in Gen. 5, Enoch seems to be the only one that had the desire to know God and He was rewarded for that.
