God is angry [John 3 v16 ]

Last night we had thunder and lightning, some old people used to say about thunder that it is God being angry,I dont thing so. Does God become angry? , it appears He does, there are many scriptures that speaks of God being angry, Psalm 7v11, tells us that God is angry with the wicked every day.How do we reconcile this with the words in 1 John 4 v16, that tells us that God is love. The fact is that even loving people become angry, so it is with God He is a righteous God, a Holy God , He hates sin, in any shape or size, and will judge it. Gods anger I believe is just and right, do we not feel anger when we read of child abuse ?, of course we do ,how much more must a holy God feel such things,I use child abuse as an example, in Gods case He hates all sin feels it deeply, yes with anger, and will eventually judge it, but God is love. God who is love thought up and brought into being , a way that could save people, you and me, Calvary, the cross, when we embrace Christ as our Saviour , then Gods anger is turned away fron us, and we have then peace with God. [Holy God we acknowledge that we are sinners, deserving of your righteous anger, and judgement, we thank You , for Jesus who died for us, so we could be forgiven , Amen .]
