According to the Unitarian Catechism the right answer would be:

38. How is God presented by his creative and providential works?

The creative and providential works of God present him as eternal, perfect, omnipotent, good, just and merciful. These qualities result from his fatherly love.

39. What do we mean: God is eternal?

When we say God is eternal, we mean that God always has been and will be forever.

Psalm 102:26-28: They will perish, but thou dost endure; they will all wear out like a garment. Thou changes them like raiment, and they pass away, but thou art the same and thy years have no end. The children of the servants shall dwell secure; their posterity shall be established before thee.

Psalm 90:2: Before the mountains were brought forth, or ever thou hadst formed the earth and the world, from everlasting to everlasting thou art God.

40. What do we mean when we say God is perfect?

When we say God is perfect we mean that all of God's creation and activity is the best and the most correct and that the instruments he uses for the fulfillment of his laws are always the most suitable that could be chosen.

   Be perfect, therefore, as your heavenly Father is perfect. Matthew 5:48.

    Can you find out the deep things of God? Can you find out the limit of the Almighty? It is higher than heaven - what can you do? Deeper than Sheol - what can you know? Its measure is longer than the earth and broader than the sea.   Job 11:7-9

41. What do we mean when we say God is omnipotent?

When we say God is omnipotent we mean that God can do all he wants, but does not act contrary to his laws.

    Jesus looked at them and said, "for mortals it is impossible, but for God all things are possible. Matthew 19:26.

42.  What do we mean when we say God is good?

When we say God is good we mean that he does only good with all of his creatures, not only with those who are good and worthy, but with those who are worthy of punishment as well.

   And he said to him, "Why do you ask me about what is good? There is only one who is good..." Matthew 19:17

    So we have known and believe the love that God has for us. God is love, and those who abide in love abide in God, and God abides in them.    1 John 4:16

43. What do we mean when we say God is just?

    When we say God is just we mean that God judges our lives and all of our deeds, rewarding the good and punishing evil. Everyone must bear the consequences of his or her life and works.

See Romans 2:6-11: For he will render to every man according to his works: to those who by patient continuance in well doing seek for glory and honor and immortality, he will give eternal life; but for those who are factious and do not obey the truth, but obey wickedness, there will be wrath and fury. There will be tribulation and distress for every human being who does evil, the Jew first and also the Greek, but glory and honor and peace for every one who does good, the Jew first and also the Greek. For God shows no partiality.

44. What do we mean when we say God is merciful?

When we say God is merciful we mean that his fatherly love makes allowances for our faults, gives us time for improvement and to reform ourselves and that he forgives us.

See:    Luke 15:11-24   - the prodigal son

45. What does all that we have learned about God persuade us to do?

All that we have learned about God persuades us to worship the one God in spirit and truth, to trust him, to love him and to live and work according to his laws.
