Hi Michael,
Christianity is not primarily about what you do and don't do. It is primarily about the living person/God, Jesus Christ, and your interactions with him. E.g., talking to him daily (about him, anything going on in your life, anything important to you, etc.) with reverence is one of the most important things you can do. Getting to know him through information about him already available (The Bible) is one of the most important things. Using that understanding to live in ways that are pleasing to him is a good goal.
The purpose of the Bible is to get to know what Jesus is like and as a result know how to please him and what displeases him. However a Jesus-centered attitude and approach to living that God wants most for you. Through this you will learn what is good (pleases him), what is not (displeases him), and what doesn't matter all that much (the things that don't affect your relationship with him).
But learning a list of do's and don'ts without understanding why is not God's #1 goal for you. In some cases, it is the best we can do—like when your pastor evaluates a situation you face and explains how God views the situation, you may need to do something even if you don't understand why (or don't want to), but most of our walk with Jesus is without a human helper by our side.
The idea that you now need to "run your new life" is a little skewed. What you need now is
not run your new life. Let Jesus be in charge of it. Ask him what he wants you to do and not do. Jesus summarizes the most important things this way:
One of the teachers of the law came and heard them debating. Noticing that Jesus had given them a good answer, he asked him, “Of all the commandments, which is the most important?” “The most important one,” answered Jesus, “is this: ‘Hear, O Israel, the Lord our God, the Lord is one. Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength. ’The second is this: ‘Love your neighbor as yourself.’ There is no commandment greater than these.” (bold mine, Mark 12:28-31, 1984 NIV)
For example, no longer watching TV because "TV is evil" is an un-thought out reason to stop watching TV. Your TV is an electronics device. It's not evil. It is used to watch/hear such a large variety of content, that it makes sense that some of it will be good, some bad, and some neither. What is it about some show that makes it good or bad? Learning
that will help you grow closer to God.
The following verse is in the Bible. It helps you understand what God wants for you in terms of your mental life.
Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things. (Philippians 4:8, 1984 NIV)
Every command from God is for your, your community's, or mankind's benefit, and obedience is your participation in God's plan to save people and bless you.
There's a lot of video games that go against what God says what is good for your mental life, but some do not (Community-made content playable through
Portal 2, a 2011 popular puzzle game, for example).
A good start is to study the Bible to learn what it means to love God, because you can love him without
feeling like you love him.
(The following verse does not explain much about loving God, but it is a start.)
“If you love me, you will obey what I command. And I will ask the Father, and he will give you another Counselor to be with you forever— (John 14:15-16, 1984 NIV)
But the Counselor, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you. (John 14:26, 1984 NIV)
