We should obtain a level of peace and groundedness in this life due to our faith, of course, but this life will always pose struggles, obstacles, suffering, doubt-that's just honesty. The "peace that passes all understanding" is rarely available in this life except for a special granting, a taste, given according to Gods wisdom. It's so good that it's virtually a taste of heaven.
None of what the norm tells us is right, in the sense that it's adequate, even if it happens to be right on the money as to its basic theology. This is because God is a direct experience after all, and can be even now to a limited degree-but so much more so when we meet Him "face to face" of course. Otherwise knowledge of God remains simply information we receive about Him.
BTW, the Law expresses love because the Law is based on love. This is why Jesus could sum it with the greatest commandments, to love God and neighbor.
