If you study the Bible, you will see that all of this death and suffering were not part of God's original plan. Because they distrusted God, the first people God created chose to listen to Satan instead of God. Since that time, everybody has to make a choice--to follow Satan or to follow God.
Take a look at look at what the Bible says God's character is. "He who does not love does not know God, for God is love."(I John 4:
"But the Lord is faithful, who will establish you and guard you from the evil one." (II Thessalonians 3:3) If you follow God and let Him guide you, your life will show these results or fruit: "But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, self-control..."(Galatians 5:22-23)
These characteristics may seem to contradict a lot of what you see in the Old Testament. However, the God mentioned in the New Testament is the same God mentioned in the Old Testament. "For I am the Lord, I do not change..." (Malachi 3:6) Sometimes the image of God in the Bible may appear to be revengeful and cruel, but that is not so. Remember God is love. God hates sin and all it does, but He loves the sinner infinitely more than we can understand. He loves the sinner enough to allow Jesus to be killed to pay the penalty of sin. "For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord." (Romans 6:23.)
God works with all of us as much as He can to get us to stop sinning and ask forgiveness for what we have done. It is totally our choice, though, because God cannot force us to obey Him. "Whoever therefore wants to be a friend of the world makes himself an enemy of God." (James 4:4) God is a God of love and mercy, but He is also a God of justice. "'The Lord is longsuffering and abundant in mercy, forgiving iniquity and transgression; but He by no means clears the guilty, visiting the iniquity of the fathers on the children to the third and fourth generation." (Numbers 14:18) When someone persistently refuse to listen to conscience and obey God, God will not "bother" that person anymore. But that doesn't happen until God has done everything He can to help that person change. God knows everything and only when God knows that nothing else He can do will change that person, He will allow him to do what he wants. In the Old Testament, when God wiped out whole tribes of people, He was not doing it out of hatred, but rather out of love. He saw that those people would not change no matter how much more time they had. If they were allowed to stay around, they would lead many others to join them in rebellion against God. Take for example Sodom and Gomorrah. If you are not familiar with the story, read Genesis 18-19. God destroyed the wicked cities, but only after Lot and his family were led out of the city by angels. If there had been ten people who wanted to follow God in those cities, God would not have destroyed the cities.
This has much to do with what is commonly referred to as the unpardonable sin. The unpardonable sin is persistently refusing to listen to God. "He who is not with Me is against Me, and he who does not gather with Me scatters abroad. "Therefore I say to you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven men." (Matthew 12:30-31) Blasphemy against the Holy Spirit is the persistent refusal to respond to the invitation to repent.
Do not refuse to listen to the Holy Spirit any longer. God promises in the Bible, "If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness." (1 John 1:9) It is not too late to change. Choose not to follow Satan, but rather to follow God. If you ask God to help you, He will. God is a God of love and He will never give up working with you until there is no hope left. Don't reject His pleas. Please choose to follow Him now.
