People that blame God for these kinds of things simply don't know Him! Now, you may say, "But I know Christians that believe that God did these things!" Yes, I am sure that you do. And they may even be actually, factually, born again. However, I can assure you that they don't have a CLOSE relationship with God. Here's what I mean. You can be a child of someone and not know them very well. Their are people that have not even known their fathers since they were very young! They are in every way children of their fathers, they are related to them, but they don't have a close RELATIONSHIP with them. They don't know how they think, what their opinions are, how they are likely to react in a given situation. BUT... they are their children! So it is with some Christians.,, they have trusted God with their eternal salvation. They have received Jesus as their Lord, but they have not drawn close to God, they haven't gotten to KNOW Him! If they had, they would know that God doesn't kill, steal, or destroy! They simply don't know him that well.
But if you will drawn nigh to God, He will draw nigh to you! (James 4:8) You CAN get to know Him that well. You can develop a close, personal relationship with Him. Then when you hear people malign God's character, you will feel about it the way you would feel if they were saying those things about your earthly father (if you have a good relationship with him.) God is a friend that sticks closer than a brother... or earthly father! (Prob. 18:24)
