Comparison is huge in our current world. Comparing ourselves to others is one of the easiest ways the devil can get a foothold into our lives, but we have no need to worry about such things. In Galatians we are called to worry about ourselves and our own actions. All Christians have different paces and paths to their walks. It’s individual. So instead of worrying where others are at, whether that's “father ahead” of “behind” us, we should be more focused on what God is doing in our lives. We can rest in him and place all our trust in him and have confidence in our own walks with Christ.
