I personally wouldn't judge them for what would they understand of righteousness until they are born of God. They will notice your lifestyle changes a whole lot more than what you will tell them. As Classic said you are a light of God to them.
Continually go to God in prayer for their sake, study your bible so that you know what it says, and be ready to give an answer when it is the time God sends them to you for an answer for your faith. If you are able, especially memorize scripture like John 3:16, Ephesians 2:8-9, Romans 10:9-10 as pertaining to salvation. Learn how that Jesus is God, know the meaning of sin, and Romans 3:23 showing that all have sinned, etc. You know what brought you to believe, and those things will help them; just allow God to do the work in them you are asking Him to do,
God bless you in Jesus' name.
I am fear to speak forward of my circumstances but I now trying to.
I cry for Father when I was in church. I am sad everyday since the time Father says that I would need to be tested, and it is around three months (starting from the very end of November).
It was like that:
1) Firstly I were informed that how my future, (I was a Christian for two years and still fresh in dealing with sin) and I was led astray by the desires of this life but God keep me back on the right after I fell into several temptations connected to the desires that caught me to sin.
2) After that, I was tested again, also about my future. Again, I was led astray by sin, and I feel the anger and certain refusal to keep on, but I am too young in faith to reject it. It keeps me on until some time, Father again inform me that I should not be tempted, and immediately I know that I was at the wrong.
3) Because I need Father really much, I kept myself in my room daily for prayers, and others reading bible. They weren't use to my lifestyle, and try to convince me to live how they are. Firstly, Father let me experience his teaching, told me not to worry and keep in heart so much about the worries and work of this life, instead encourage me to be active in connection to bible. These days, I have make up my mind not to being tempted, learn to free myself from the trick of temptations, and leave myself with prayers and bible, and I am able to do it, I thank Father for the help, may His name be praise.
4) But on the other side, Satan keep his work on me during my prayers, bible reading, I always get discouraged, and feeling lifeless but thank God after speaking in this community, peace be with me. My parents had not allowed me to attend church for prayer session, and even worship service. I always felt discouraged at first, but now I see these community as my very fellowships in the body of Christ. And my soul turn in joy again, before that I was discouraged because of my attitude (acting cowardly and resist to speak of) and fear that my English wouldn't help. And I am shy to speak that I am weak, sometimes need more encouragement for prayers when I am discouraged by Satan, sometimes need more conversations to share about standing more firmly in Christ. I still have two months to go, hopefully by the community, I could help myself in my faith, and be strengthen, in Jesus name I pray.
5) At first, I feel very hard to cope with. Because before and after the test seems quite far for me. At first, I still remember when I was firstly connected to Father, (I were hide with sins yet God does not exposed it to my conscience, only after by daily growing in Christ I came to understanding of holding my faith), Father show me the book with every pages whenever it flipped it came out full of wisdom; and after that I was seriously tempted, following the streams of lies that it caught me so much after I aware and come back to Father's side. There's periods and not once, every time when my faith is with me, I weep bitterly, sometimes talk to Father in such ways of complaints because I already cannot hold myself thinking positively. I know that I am sinning too before the test, but before it wasn't so discouraged by Satan and I feel peace is with me, I still remember there's voices inform I have to go through some test but after that God will bring me back to faith, that time I were fear and reject to believe, but after that I really faced the test (it gone so horribly and until the test end and Father restore my faith then I only remember what He told me was true). Yet this time (test has not finished) although it was harder but Father help me to reveal the sin (hatred), teach me the way to live more accordingly to his standard, and what doubted me was the discouragement that Satan work on me, sometimes when I were unbearable I would cry to Father in sort of complaints, I wonder anyone if time by time being disturbed by his flow of lies, hatred, evil thoughts and become discouraged, what would help them with it? Times by times I read the bible, I didn't get inspired (if there is, maybe it was my doubts that caught me to fear of listening, as I was so weak on my faith that I only able to differentiate the source of voice with the feelings) and discouraged, sometimes the work of Satan like painful thorns in my body come unreasonably in my understanding, that's how when I always end up lost, sometimes when I am in prayer, the sleepiness or flow of lies start pouring on me and although I pray fervently it keeps on obstructing my faith to be strengthen, to believe, and sometimes I have my prayer long without answered, the discouragement from Satan keeps on attacking me, leaving me a hard days of holding my faith firm. Sometimes, I cry to Father what I had learn through test, I feel that I keep on failed when Satan's work struck me heavily, keeping myself in the life of sin yet I am encouraged when Father says I learn, and come more close to Him after what I have faced.
Thank you very much for your concern for me. God bless you in Jesus name, may happiness in Lord always be with you.
