Yes, God does get angry. 

Psalm 7:11 (NKJV), “God is a just judge, And God is angry with the wicked every day.”

Psalm 76:7, “Thou, even thou, art to be feared; And who may stand in thy sight when once thou art angry?”

Psalm 79:5, “How long, O Jehovah? wilt thou be angry for ever? Shall thy jealousy burn like fire?” 

Psalm 85:5, “Wilt thou be angry with us for ever? Wilt thou draw out thine anger to all generations?” 

No. God’s anger is for a period of time in order to bring repentance. Psalm 30:5, “For his anger endureth but a moment; in his favour is life (the reformed of mankind will receive eternal, perfect life on earth): weeping may endure for a night (the nighttime of sin), but joy cometh in the morning (in the morning of Christ’s reign on earth).”

Isaiah 12:1 (NIV), “In that day (the Millennial day) you will say: ‘I will praise you, LORD. Although you were angry with me, your anger has turned away and you have comforted me. Surely God is my salvation; I will trust and not be afraid. The LORD, the LORD himself, is my strength and my defense; he has become my salvation. With joy you will draw water from the wells of salvation.”

Compare this with Revelation 22:17 (NKJV), “And the Spirit and the bride say, ‘Come!’ And let him who hears say, ‘Come!’ And let him who thirsts come. Whoever desires, let him take the water of life freely.”

Yes, there will be a great time of trouble, a time when God displays His fierce wrath, but afterward, on the rubble of the destroyed nations, God will pour out His love. (See Daniel 2:44.)

Zephaniah 3:8 (NIV), “‘Therefore wait for me,’ declares the LORD, ‘for the day I will stand up to testify. I have decided to assemble the nations, to gather the kingdoms and to pour out my wrath on them–all my fierce anger. The whole world will be consumed by the fire of my jealous anger. (God’s anger is like a jealous fire, but it can’t be literal fire because people are still left on the earth). Then I will purify the lips of the peoples, that all of them may call on the name of the LORD and serve him shoulder to shoulder.’”

Ezekiel 16:42, "So will I cause my wrath toward thee to rest, and my jealousy shall depart from thee, and I will be quiet, and will be no more angry.”
