We do not have to fear God since he is God with and for us, and our response to him must only be a response of love.
We do not have to do anything nor can we do anything to obtain the love of God. It is given freely simply because God wants to. All we have to do is receive it with openness and humility.
We must accept that each of us is a sinner and so in need of the saving grace of God. Once we accept this reality then we become more accepting towards others because we realize that we are in the same situation as they are. We are not better than they.
