Is Dancing Wrong?
Second, continue communicating with your dad. Once you start receiving outside support, you'll gain more confidence to talk with your dad about your desire for a meaningful, deeper relationship. Tell your dad you love him. But remember: Most alcoholics have a difficult time with intimacy. You might have to lower your expectations of a "perfect" home and relationship. As you seek a healthier relationship, don't be afraid to call your dad's problem by name. He's an alcoholic; tell him you believe he can get help for his alcoholism. You can even help him find a local chapter of Alcoholics Anonymous by checking the phone book or going to www.alcoholics-anonymous.org.
Third, don't neglect yourself and your own needs. There is always the temptation to feel like you're responsible for somehow "fixing" your dad. You're not. You are responsible for taking care of yourself, so be sure you do. Build good friendships. Get exercise. Eat healthy. Find ways to relax and simply enjoy life. And be sure you stay away from alcohol and other substances. As strange as it sounds, children of alcoholics often turn to alcohol or other drugs to solve their problems. Don't give in to the temptation.
Finally, don't neglect your spiritual life. I like these verses: "You, Lord, give true peace to those who depend on you, because they trust you. So, trust the Lord always, because he is our Rock forever" (Isaiah 26:3-4, New Century Version). God doesn't promise us an easy life, but he does promise to walk with us through our times of trouble.
As a Christian growing up in a family crippled by alcoholism, I felt at times like my faith was misunderstood. I wanted the kind of relationship with my parents that you want with your dad. And to be honest, I eventually gave up much hope in the situation ever changing. The fervent prayers I prayed in high school became less regular.
But God did get ahold of my family. It wasn't while I was still in high school, but today we have the relationship I always longed for. Keep praying for your dad, and don't give up hope.
I Don't Get the Trinity
Why do we call God "Father"? And what role does the Father have in our lives that's different from Jesus and the Holy Spirit?
To answer your first question, we call God "Father" because Jesus said to. He instructed his disciples to pray to "Abba" (Matthew 6:5-15), which means "Daddy" in the English language. Never before had God, the almighty creator of the universe, been addressed so personally and informally in prayer. With just one word, Jesus showed that God is our loving Father, and we are his children.
Now about the role of the Father. Your question deals with one of the great doctrines of Christianity called the Trinity. Although it's a very difficult idea to grasp, we believe in one God in three persons: the Father, the Son (Jesus), and the Holy Spirit. Each person of the Trinity has a distinct role. Generally speaking, God the Father is the creator, Jesus is our Savior, and the Holy Spirit lives in each Christian, comforting, empowering and leading. But even that's an oversimplification; in reality, the roles are shared by all three persons of the Trinity. The Trinity is a complex concept, and even the world's top theologians have difficulty defining the roles of all three persons.
