I can only share my stories and perceptions of life at this point.
Share your stories. They are your witness. There you only talk about yourself, and that's what you can talk about, because you know.
Your perceptions are private. No two people are the same, and God is no communist with a one size fits all solution. So what worked for you, your perception of the gospel doesn't necessarily fit for others. Plus: We are all on a journey with different starting points. When you try to make people go your way you might be a bad guide because they might walk into the wrong direction or they might approach you but not come closer to God in their effort to get to your place.
If you tell your story about how you try to get closer to God, they might feel the demand to do so as well. Their way will be different but their destination is the same as yours.
Frankly, this verse scares the crap out of me! It makes me think about all my suffering in my life because I want to know why.
See, in my case I've been around that place briefly. Today I wouldn't say the bible is the true word of God, because it is no word. I'm more with Martin Luther now who said the word of God is the living the preached word in the very moment it is preached and speaks to the heart. The mere written letters on a paper are not the word of God per se. If this was the case, God's word could be mastered. I can put a book into my pocket and thus carry God around that way. I can interpret these written words in any way I like. The bible has been used to justify slavery, bigotery, even the Nazis here in Germany abused the bible for their cause. This is why I say the bible is just a book. A good book, an important book, but a book, and without the Holy Ghost it helps us nothing, on the other hand the Holy Ghost can also work without the bible (though the bible can help you distinguish the Holy Ghost from other spirits)
You say you are scared, that is another point. I arrived at what Paul wrote: Nothing can separate me from the love of God which is in Jesus Christ our Lord and saviour.
We Christians have no real reason to fear anything, because we are saved and we know it. I cannot tell you why exactly you had to suffer, but sin might play a role. Now get me right, I don't say sin isn't there or not so big a deal. Sin is hell to those who don't believe, because they have no hope to get away from it. We, as Christians, do know we are sinners, we do know we cannot overcome sin by ourselves, but we can take up he fight and we can rely on the fact that God is for us and that whoever might be against us is not as big as God. So if ever we do sin, we can repent without fearing the consequences (this doesn't mean there were no consequences), we can go on and do our best to do better in the future.
So don't be afraid, neither of sin nor of suffering. For some of your suffering others might be accountable. For some, you yourself might be accountable. I don't know any of this. All I know, it's neither you nor the other sinners who are the enemy. The enemy is sin, and sin won't prevail. Because as Christians we are strong to forgive others, what they did to us, and as Christians we can be assured that God does forgive us our wrongs, so sin won't take us captive any more, sin will not breed more sin as soon as we confess our own sinfulness. Once I can say I am a wicked sinner and for my sin alone people do suffer, I do not need to hide my sinfulness with more sins. The vicious circle is broken, we are free at last.
God bless
