Gods forgiveness is for everyone.

““For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.” John‬ ‭3:16‬ ‭ESV‬‬

I don't think God even consider forgiving anyone. Forgiveness is His nature, so He forgives everyone and everything before the sin is even made. We are told to forgive the same sin again and again and be quick about it. God must be able to do even better than that.

God doesn't discriminate between us sinners. We shouldn't either. This quote is not about discriminating Christians from non-Christians, but humans from God. God has the power, we are the powerless. Only God can clear our consciousness.

We can only receive forgiveness if we trust that we can be forgiven. This quote confirms that we can. If Christians say it is only meant for Christians they have missed the point and distorted the meaning. No person is more superior than another in Gods eyes. Everyone deserves a second chance and a third, forth and so on.

A lot more can be said about this quote of course, because it is a very powerful sentence, but I just wanted to say this now because it annoys me when some Christians think God forgives them because they believe in Jesus (and those who are not calling themselves Christians will not be forgiven) and not simply because they trust they will be forgiven.

To perish means to die. Die spiritually. If we are burdoned with sin we feel disconnected to God our source of life, love, wisdom and happiness; We feel dead. To perish doesn't mean that some people will not have eternal life, literally! It means that if you are burdoned with sin your life are limited, you will not feel free, one with God and eternity. 

No, you don't lose God by making sins, but if you think God rejects you you will feel lost.

When one has sinned the sin becomes a wall between him and God. It is very important then to talk to God about it, ask for forgiveness and a way to make things better, knowing he listens through any wall. I think people can forget about God if they sin and think the sin is unforgivable. But who are they to judge? How you handle sin is a test on how much you love God and believe in His love. Also how you respond to other people who sin by hurting you. Do you forgive? If you don't you may not think God will forgive your sins either, because people have a tendency to project their own concepts on others. Even on God who is more loving than we can ever fathom.
