Obedience. Start Intimacy with God. Obedience. Start there. Why? Well, for example, John there. Why? Well, for example, John there. Why? Well, for example, John 15:14, Jesus says, "If you do what I 15:14, Jesus says, "If you do what I 15:14, Jesus says, "If you do what I command you, you are my friends." command you, you are my friends." command you, you are my friends." By the way, Psalm 66:18 says, "If I By the way, Psalm 66:18 says, "If I By the way, Psalm 66:18 says, "If I cherished iniquity in my heart, he would cherished iniquity in my heart, he would cherished iniquity in my heart, he would not hear me."

  2. not hear me." not hear me." Now, see, Now, see, Now, see, let's I can't tell you how many people I let's I can't tell you how many people I let's I can't tell you how many people I know who found that they lost their know who found that they lost their know who found that they lost their intimacy with God, their friendship with intimacy with God, their friendship with intimacy with God, their friendship with God, because they weren't obeying him. God, because they weren't obeying him. God, because they weren't obeying him. Now, here's where Aristotle is kind of, Now, here's where Aristotle is kind of, Now, here's where Aristotle is kind of, this is probably why Aristotle was this is probably why Aristotle was this is probably why Aristotle was concerned about talking about friendship concerned about talking about friendship concerned about talking about friendship with God or the gods. with God or the gods. with God or the gods. He says, "No, we're too different." He says, "No, we're too different." He says, "No, we're too different." Well, I tried to show you that because Well, I tried to show you that because Well, I tried to show you that because of biblical theology, we're not too of biblical theology, we're not too of biblical theology, we're not too different because of the image of God in different because of the image of God in different because of the image of God in me and you, and because the atonement me and you, and because the atonement me and you, and because the atonement and the incarnation and the incarnation and the incarnation on God's side, because the image of God on God's side, because the image of God on God's side, because the image of God on our side, on our side, on our side, stunningly we can be God's friends. But stunningly we can be God's friends. But stunningly we can be God's friends. But the fact is that God is not just like the fact is that God is not just like the fact is that God is not just like us. Yes, he's a lot like us only because us. Yes, he's a lot like us only because us. Yes, he's a lot like us only because of the incarnation and the atonement, of the incarnation and the atonement, of the incarnation and the atonement, but he's not just like us. And we must but he's not just like us. And we must but he's not just like us. And we must never think of friendship with God as never think of friendship with God as never think of friendship with God as treating him just like us. Uh for treating him just like us. Uh for treating him just like us. Uh for there's two reasons why obedience is there's two reasons why obedience is there's two reasons why obedience is necessary for friendship. Number one, necessary for friendship. Number one, necessary for friendship. Number one, if he's if you obey him, you're going to if he's if you obey him, you're going to if he's if you obey him, you're going to become more like him. It's called become more like him. It's called become more like him. It's called holiness.

  3. holiness. holiness. And all of you know who have had And all of you know who have had And all of you know who have had friendships for a long period of time is friendships for a long period of time is friendships for a long period of time is friends rub off on each other. You know, friends rub off on each other. You know, friends rub off on each other. You know, friends rub off on each other. They they friends rub off on each other. They they friends rub off on each other. They they they they uh they sharpen each other. they they uh they sharpen each other. they they uh they sharpen each other. They move each other more toward one They move each other more toward one They move each other more toward one another in many ways. You have to. Now, another in many ways. You have to. Now, another in many ways. You have to. Now, Jesus Christ is already done his part. Jesus Christ is already done his part. Jesus Christ is already done his part. He's come an enormously long way to He's come an enormously long way to He's come an enormously long way to become like us. It's called the become like us. It's called the become like us. It's called the incarnation, the atonement. Okay, that's incarnation, the atonement. Okay, that's incarnation, the atonement. Okay, that's a long way. But it's only through a long way. But it's only through a long way. But it's only through obedience you start to move closer to obedience you start to move closer to obedience you start to move closer to him. you start to become more like him. him. you start to become more like him. him. you start to become more like him. And therefore, without obedience, there And therefore, without obedience, there And therefore, without obedience, there can't be friendship because friendship can't be friendship because friendship can't be friendship because friendship in friendship people converge. They come in friendship people converge. They come in friendship people converge. They come together. They they they learn from each together. They they they learn from each together. They they they learn from each other. They they become more like each other. They they become more like each other. They they become more like each other in many ways. But here's a second other in many ways. But here's a second other in many ways. But here's a second reason why obedience is necessary for reason why obedience is necessary for reason why obedience is necessary for friendship with God. And that is, isn't friendship with God.

Summary

Biblical theology makes friendship with God possible, fostering a framework for prayer through obedience. Scripture like John 15:14 and Psalm 66:18 highlight obedience as crucial for maintaining intimacy with God. The takeaway is that through Christ's incarnation and atonement, and our own obedience, we can become more like God and cultivate a genuine friendship.
