Well, God wasn't being destructive to the Christians, or Jews, was he? He was only destroying the enemies that would have their heads, so they could be free. The whole time those guys were there, and the people who had to be killed never went to them. And if God was so deadly, why are you still standing? Why is anyone breathing? Because that would sort of kick his son, Jesus, in the face. After he y'know, died for our sins, and rose again, and promises salvation. He loves us Shy, more then anything. I /promise/ you, a promise that won't be broken, that if you follow Jesus in your life, your life will be so much better. If you study his Word, and follow it, it will be so much better. All miracles listed were Old Testament, I believe. Things weren't fun then, I gather. And as for the flood, not one person on the earth was good, save Noah. They were an ancient New york, but with 100x more sin, and the entire earth was it. He got rid of them all, but cried after, and promised to never do a flood again. An all hating, all deadly God wouldn't cry from his actions, would he? It shows me that he loves us. And he doesn't need to do that again, since Jesus came, and took our sins to the cross. Same thing for Sodom and gommorah. God said, "Yea, if but 1 good man could be found, it would be saved." There was not one. Going on, Jesus died for us, as said. He knew all along that he was going to be put to death, and he went anyway. He allowd himself to be killed (Horribly.), what all powerful all hating God would send his son to the cross for our sins, so that we may be saved? And you might list off some bad times, some trials. In the words of TD Jakes, "If it is not used to lift you up, and grow you, it is not of God! It is not of God!". If the trials you face are not to make you a wiser, or stronger person, do not blame God. God tests us as people to be the best we can be, to speak the truth, to be kind, and to love. Not to kill, slaughter, and hate. If the entire world turns against you, guess who's still there that matters? Jesus Christ.
The Holy Spirit is not evil, or destructive.
