obi you have done a great job! 
I would just like to add that once you are aware of sin to wilfully multiply it is not wise.
The way to avoid the judgement we will all face concerns true repentance which comes before seeking forgiveness. First of all though we need to understand what sin is so that we can truly repent and ask for forgiveness. Sin has become a dirty word as nobody likes to acknowledge such a thing nowadays since it then has to be dealt with.
Sin is anything which makes us fall short of the glory of God.
God is the one true God. He is pure and cannot, and will not, have impurity in His presence which is why we will all be judged at the end of time and some will be sent away from God's presence and go to hell and the saved will go to heaven.
Jesus, who is part of the Triune Godhead, paid the penalty for our sins by His death on the cross and that forgiveness is available to all those who believe, confess their sin, repent and ask for forgiveness.
Jesus said "no one comes to the Father but by me" so if we want to be accepted in the beloved we have to follow the steps outlined.
Oh, and just because you are a Christian it does not mean you suddenly become perfect and never sin again it just means that you are now aware of your sin and know that you should be doing your best not to do that sort of stuff. We all sin every day so have to keep coming to Him and confessing, repenting and being forgiven. It is hard work but we are promised that the rewards are great!
