God loves us unconditionally, no matter what we do, God will still love us, but there are principles upon which God's protection works.

Shadrack, Mishak & Abednego went through a fiery furnace, not because there was sin in their lives but because God allowed it to happen to grow their faith and also for others to see the strength and character of his true worshippers and believers, and for us to see that during the fiery furnaces of life God himself will be with us as there was a fourth person with the three of them in the middle of the fiery furnace, and that fourth person was Jesus, and not one of the hairs on their bodies was singed and they enjoyed God's piece and protection amidst the fire, but the kings guards who threw them into the fire were burnt to death in their haste to get rid of them on the King Nebuchadnezzar's orders.

And sometimes, we need to be prepared to make sacrifices in this world for a good cause, just Like Jesus Christ was prepared to be tortured and even give his life to pay the price for our sins.

But there are times in our lives when we are experiencing tribulations due to there been sin in our lives, Jesus said if you so much as look with lust in your eyes, you are committing adultery before God, we should not even hug in a way in which we enjoy that hug more than what we should, as this is sin before God and removes the shield (Prov 2:7) that God puts over us, that's when Satan is able to enter your life and rob you of God's peace, either through your health, finances or family.

Also God who is a just God and without partiality blesses us for living according to his standards and curses us when we live according to our own manmade standards that invloves sin.Deut 26, 27, 28 & Rev 2:22-24 - Jesus explains to John how he'll deal with the New Testament Church if they entertain sin or become luke warm.

The key is to discern by the guidance of the Holy Spirit, are you going through a fiery furnace for God to grow you or are you going through tribulations due to something in your life not been right with God.

Your sins also affect the shield over your children, David had an affair with a woman, and had her husband killed and as a result God pronounced through his prophet that the child from the affair won't live and the child died after 7 days after been born.

On a macro economic level (nation wide), the children will grow up facing the consequences of the sins of their parents on a national level.

Generational curses are also passed down for up to four generations, (Exodus 20).

Just to expand on a national level, as we as a society drift further from God and God's word so we as people become more disorientated ito what is right and what is wrong, and are more prone to developing our own values that are contrary to the Word of God and become more wicked and perverted and are more prone to the influence of Satanic forces, and this is when things happen such as the Holocaust(millions of Jews were killed by Nazi Germany) and roughly a million Cambodians were killed by Pod and his regime in their domination, and in Rwanda roughly a million Hutu's and Tutsi's killed each other from racial tensions and so the list goes on.

God is not going to just fix this world on his own, he gave us mankind the power and authority to rule this world in a partnership with him, if we don't do our part he won't do his, as the initiative is with us, we've been given the right to choose to partner God or not to partner God, its our choice.
Its our choice to partner in a constant relationship through prayer, holiness(living according to the word) and fasting, which unleashes God's power to influence people positively and reduce the power and influence of Satanic forces.

The Goodnews is that when we truly repent through the blood of Christ, the sins are washed away and eternal life is inherited and a new beginning is put in process, where you work through the consequences of your sin(e.g. former drug addict will work on getting spiritually strong again etc or as nation, the nation will begin to heal and move forward) and heal from past sins and start to move forward in Jesus name.

Sin takes many forms:
lust (fornication, homosexuality(Jesus said marriage is between a man and a woman.), adultery, lust of the eyes, masturbation, even hugging someone in a way in which you enjoy the hug more than what you should who is not your spouse etc)
greed( chasing money, not tithing, stealing etc)
envy , covetnous, jealousy, pride, sloth, cruelty, idolatry, bearing false witness, lying etc
idolatry(making anything else your god other than the true living God (The Father, The Son & The Holy Spirit).

Abortion (Jer 1:4 - I knew you before I formed you in your mothers womb), then its safe to say at the moment of conception there is life.Why does God breathe a spirit/life into a mother's womb in a nation where most of the children starve to death, it's because God is bound by a covenant with mankind that when we conceive he automatically conceaves as well and without partiality i.e it just happens, the only time God does not breathe life into the womb even apon physical conception in the womb of the mother of the fertilised egg is when the couple are oprerating under a curse which is manifesting in barroness. Everything we do here on earth in the natural results in a action in the spirit realm re life/death, blessings/curses and either for Good or evil. So from the moment there is physical conception there is also a spirit birthed in the spirit realm by God that is transferred via the Holy Spirit and the Lords Angels into the womb of the mother, unless the couple are cursed which is manifesting in baroness, so yes, Stem cell research that involves the female egg of the woman been fertilized by a man's egg results in a spirit been birthed by God, so stem cell research of this nature as explained above is an abomination and should be stopped.
Murder, including bearing malice, having hate for another person, also killing as a act of war/military action, These soldiers that go and kill, are cursed and all have God's shield removed and their consionce sneered, that's why when they come back, they are haunted by demons in their sleep or are plagued with health/family problems/tragedies, because they don't have God's protection anymore until they repent. Mankind must learn the Mandela/Ghandi way is the only way, and sort things out in a non violent unbiased way - see page on Prayer & Fasting for more on this.
Sin of omission i.e. not doing what you know you ought to do or not doing what God has told you to do etc.
Blasphemy(using the lord's name in vain)
Cursing people(wishing ill toward someone or cursing them with the tongue)
Disrespect for parents, you don't always have to agree, but when you disagree, do it in a respectful manner, (where abuse is involved please get your pastor and the local authorities involved)
Witchcraft, Ancestral worship, Soothsayer, Mysticism, (there is one mediator between man and God and that is Jesus Christ, the correct way to pray when asking for guidance is to our Heavenly Father, in the name of Jesus Christ by the guidance of the Holy Spirit.) Also please note, Satan comes as a angel of light, or pretends to be your dead loved one to deceive u so when you entertain these spirits, it opens the door for satanic influences in your life, stay away from this, rebuke these spirits in the name of Jesus Christ and then go into worshipping God if they come to you. If you want advice, ask the Holy Spirit, if you have a loved one that has passed on, stop worrying about them, it won't change anything, leave this stuff alone, its extremely dangerous, this weapon of Satan is getting stronger and stronger in these dangerous times we are living in. Jesus spoke to Elisha and Moses on the mountain, Jesus been God can do this, none of us of are God and are expresslly not given permission to entertain this stuff, so leave it alone.
