because of your sin and my sin

To know the answer to this question one must know what sin is. Catholic Church has divided sin into two principle categories, viz., mortal sins and venial sins. The the list consists of seven deadly sins, wrath, greed, sloth, pride, lust, envy, and gluttony.Another list of bad things, in addition to seven deadly sins given this time by the Epistle to the Galatians are adultery, fornication, uncleanness, lasciviousness, idolatry, witchcraft, hatred, variance, emulations, wrath, strife, sedition, heresies, envying, murders, drunkenness, revelings, etc. Religion tells us that the tendency to commit sin men had inherited from their first parents. Man and woman God had created were not perfect. He devised a way so they may get rid of their sinful tendency. He banished them out of the Garden of Eden, and they he asked them to toil and earn their bread from the sweat of their brow. In Noah's time after the tendency to commit sin had reached alarming proportions, God chose to destroy the world along with all the living things except Noah and the creatures, Noah chose to save. Thereafter, God had established a covenant with men, that whenever man will find impossible to live according to his given nature, he would come and save them himself. This is what we know as the word of God. It is written in John 1:1, "In the beginning God gave his word; God kept his word and he came as his own son to abide amongst us". I did not reproduced it adverbatim what John said, but I have given the correct interpretation of it.

God is counting on you to sin. So much is learned through mistakes than anything else.

another no here. that's not part of my belief system.

I do believe that Christ suffered in order to to save us from our sins. Although he did it already, we still commit mistakes but God forgives us when we ask for forgiveness.

Of course! And, he wasn't only nailed on the cross to redeem us, but it was a message that shows how God forgives mankind for all of our sins.

No to all particulars.

i believe that he was nailed in the cross because of our sin, not only to redeem us, but also for a demonstration of love for men and women. and the real message i think, is that if He did it to redeem us, also we can do good deeds and sacrifices to help less fortunates, friends, people...
