3D living is a framework for operating successfully in the Zone of the Unknown.
Walk across the room people are people who consistently look for ways to:

D #1 = Develop Friendships

Luke 15: [1] Now the tax collectors and "sinners" were all gathering around to hear him. [2] But the Pharisees and the teachers of the law muttered, "This man welcomes sinners and eats with them."

[3] Then Jesus told them this parable: [4] Suppose one of you has a hundred sheep and loses one of them. Does he not leave the ninety-nine in the open country and go after the lost sheep until he finds it? [5] And when he finds it, he joyfully puts it on his shoulders [6] and goes home. Then he calls his friends and neighbors together and says, ‘Rejoice with me; I have found my lost sheep.’ [7] I tell you that in the same way there will be more rejoicing in heaven over one sinner who repents than over ninety-nine righteous persons who do not need to repent.

D #2 = Discover Stories

John 3: 1-5: [1] Now there was a man of the Pharisees named Nicodemus, a member of the Jewish ruling council. [2] He came to Jesus at night and said, "Rabbi, we know you are a teacher who has come from God. For no one could perform the miraculous signs you are doing if God were not with him."
[3] In reply Jesus declared, "I tell you the truth, no one can see the kingdom of God unless he is born again."
[4] "How can a man be born when he is old?" Nicodemus asked. "Surely he cannot enter a second time into his mother’s womb to be born!"
[5] Jesus answered, "I tell you the truth, no one can enter the kingdom of God unless he is born of water and the Spirit. [6] Flesh gives birth to flesh, but the Spirit gives birth to spirit. [7] You should not be surprised at my saying, ‘You must be born again.’ [8] The wind blows wherever it pleases. You hear its sound, but you cannot tell where it comes from or where it is going. So it is with everyone born of the Spirit."
[9] How can this be?" Nicodemus asked.
[10] "You are Israel’s teacher," said Jesus, "and do you not understand these things? [11] I tell you the truth, we speak of what we know, and we testify to what we have seen, but still you people do not accept our testimony. [12] I have spoken to you of earthly things and you do not believe; how then will you believe if I speak of heavenly things? [13] No one has ever gone into heaven except the one who came from heaven – the Son of Man. [14] Just as Moses lifted up the snake in the desert, so the Son of Man must be lifted up, [15] that everyone who believes in him may have eternal life.

 
D #3 = Discern the Next Step

Mark 3: 1-6:  [1] Another time he went into the synagogue, and a man with a shriveled hand was there. [2] Some of them were looking for a reason to accuse Jesus, so they watched him closely to see if he would heal him on the Sabbath. [3] Jesus said to the man with the shriveled hand, "Stand up in front of everyone."
[4] Then Jesus asked them, "Which is lawful on the Sabbath: to do good or to do evil, to save life or to kill?" But they remained silent.
[5] He looked around at them in anger and, deeply distressed at their stubborn hearts, said to the man, "Stretch out your hand." He stretched it out, and his hand was completely restored. [6] Then the Pharisees went out and began to plot with the Herodians how they might kill Jesus.
