If we don't believe, we can't love and also we can't fear the GOD. In other words we can say that we never to be a perfect man. Because GOD's fear makes us prevent from doing any wrong work and Love makes us new.source
We have to fear for all evil works .Because GOD is wathing everything and HE will reward or punish as per our work.
But love requires no condition, not be feared also. What you had done wrong that only submit or we have to surrender all to GOD. Then only your life will be change.
God blesses to all.
