1. How can I know that Jesus has forgiven me ?
Ephesians 1:12 > trust in Christ for salvation, if you have not. Trust Jesus who died for our sins to forgive you. And, by the way, be encouraged that every one of us needs Jesus on the cross and how Jesus shed His own blood for us; and Jesus loved us and did all He did on the cross for us > Galatians 2:20.
And, like others are saying, do not be concerned only about one or two sin issues. We all need correction of much more than one or two sin problems. And the main correction has to do with how we are, spiritually, and how we are submissive to God or not, and loving any and all people or not, and how we relate in love. So, this one action or that one deed might not be what we really need to be concerned about so much, though any wrong thing is wrong.
And you need to keep your attention to God and His good >
"Set your mind on things above, not on things on the earth." (Colossians 3:2)
2. How bad do you think it was an act ?
I don't think "how" bad it was is the main thing. Most of all, you need your attention to better things, and being encouraged to know how God is generously forgiving. But in the process of being and living forgiven, we need to also be all-forgiving. So, it might be more important to evaluate how well you appreciate our Father's forgiveness and therefore you are going to lovingly and generously forgive others and pray blessing to others. If you let certain isolated things keep your attention away from loving, this is what is really bad!! So, what matters most is not how bad is something which is wrong, but how can it keep us from enjoying God and submitting to Him in His peace (Colossians 3:15) and how can it keep us from being attentive to loving others and helping them to discover how to love?
3. Please explain what you meant earlier by one could feel that a bar code is some sort of a mark; and pressing it against your forehead might be imagined by some to be poetically like taking the mark of the beast on one's wrist or head. ( please answer what you mean by that and what does poetically like taking the mark of the beast mean)
What I mean is that Revelation says that certain people will receive the mark of the beast on their forehead; so if you pressed a bar code to your forehead, in connection with your mother talking about bar codes being somehow a thing of the beast, pressing a bar code to your forehead could somehow seem similar to receiving the mark of the beast. And so, it could be "poetic", since it is seen to be somehow similar. I say it could "seem" so; however, I would say that really it would not have any resemblance to the real receiving of the mark of the beast . . . because of my answer below to "5."
4. Once forgiven will I have to answer to this on Judgement day ?
no > if a person becomes a Christian, he or she becomes a new person in Jesus > you might read and feed on 2 Corinthians 5:17, and consider how this means to become "born again" > you become a new person who leaves behind all of your past. And if you become saved, this means you get started in trusting Jesus to correct you and teach you how to love, and you learn to live in Jesus Christ's
"rest for your souls." Please see Matthew 11:28-30 and pray about this and trust God to do this with you.
If you become a new person, you no longer are the one who did your past wrong things and things which might not have been obviously wrong. So, how can God charge you for sins of that old person who no longer exists?? Plus, you are now into learning how to love, instead of doing that past stuff; so it is not even practical for God to now hold you accountable for what you don't even do and do not have the character to do . . . or at least you are growing in love so you do certain things less and less > in Jesus, we are becoming love persons, instead of who we were while doing our past sins. But we are not perfect; so we can give in to wrong things, still. But, also, we are discovering things that are wrong, which we might not have thought to be wrong > such as unforgiveness, one example of something perhaps much more dangerous and destructive than pressing a bar code to your head when that does not even really mean much to you. Invest your attention, then, in finding out how God has us loving. Seek His correction > Hebrews 12:4-10.
5. what do you think the mark of the beast will be when it's here and/or do you think anybody has the mark of the beast now ?
I consider > it is not necessarily about an outward thing put on a person. But in any case we need to make sure we do not have in us what could make us able to accept the mark. In us, we need to make sure Jesus is first so that we would not worship the beast and take his mark. And we need to be strong in Jesus so we are ready to have our heads cut off, rather than bow down to Satan and his wicked beast. And if you know how love is, it should be "easy" to not want to go along with Satan and his miserable and ruined kingdom of selfishness. Make sure we do not have
"love of money" (1 Timothy 6:10); if we depend on money and food and being able to buy and sell things, we could be scared and pressured into accepting the mark of the beast so we can have things money can buy; so it is important to know our Father is the One to take care of us, and He cares about us more and better than we can worry and care about our own selves >
"casting all your care upon Him, for He cares for you." (1 Peter 5:7)
And there is always more to learn; and it is good to share with mature Jesus people who help you get real with God and learn how to relate in love, while growing in ability to keep your mind and attention where you belong. So, don't isolate yourself, including getting isolated with pleasures and problems and questions which cut you off from people who are good for you.
