And God is not only love. In the Old Testament times much meaning was attached to names. Often, they'd use a play on words to take a name and use it to convey a quality of that person. God revealed various dimensions of His persona through the use of many and varied names for The Father, The Son and The Holy Spirit in the Bible.
The most comprehensive list of His Names I could find online is here: 900+ Titles and Names of God. I admire that they have scripture references on many.
Yes, our God is Good, He is Love, He is Abba Father, He is Savior, He is Friend, He is Mediator. Many fuzzy, warm, wonderful things. But the part that is being watered down every where you look now days to "tickle the ears" of those who prefer to live in sin is that He is also a Holy God that cannot even look upon sin. He is also the Righteous Judge who will call every living soul to account for their life.
God does have nothing but mercy to give to all who admit they are sinners and repent of it, accept His Son's gift of salvation paid on the cross for their sins and turn from living a lifestyle of sin. Those who ignore this invitation or refuse it, will find themselves told on the great judgement day, "23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity."Matthew 7 - KJV
