During the mid 80's in Utah, there was a great revival where Christians were sharing with Mormons. One church grew from 60 to 300 in a year, others doubled in size. Then a seminarian cam in and promoted the idea of friendship evangelism, and the revival died. As I said, I like the way you think, I just don't think it comes from that scripture.
People share what they love. They talk about TV shows or movies at work. If a guy is embarrassed to be seen with his wife, does he really love her? I don't need scripture to make that case but we could use:
Luke 7:36-50
Much Forgiveness, Much Love
36 Then one of the Pharisees invited Him to eat with him. He entered the Pharisee’s house and reclined at the table. 37 And a woman in the town who was a sinner found out that Jesus was reclining at the table in the Pharisee’s house. She brought an alabaster jar of fragrant oil 38 and stood behind Him at His feet, weeping, and began to wash His feet with her tears. She wiped His feet with the hair of her head, kissing them and anointing them with the fragrant oil.
39 When the Pharisee who had invited Him saw this, he said to himself, “This man, if He were a prophet, would know who and what kind of woman this is who is touching Him—she’s a sinner!”
40 Jesus replied to him, “Simon, I have something to say to you.”
“Teacher,” he said, “say it.”
41 “A creditor had two debtors. One owed 500 denarii, and the other 50. 42 Since they could not pay it back, he graciously forgave them both. So, which of them will love him more?”
43 Simon answered, “I suppose the one he forgave more.”
“You have judged correctly,” He told him. 44 Turning to the woman, He said to Simon, “Do you see this woman? I entered your house; you gave Me no water for My feet, but she, with her tears, has washed My feet and wiped them with her hair. 45 You gave Me no kiss, but she hasn’t stopped kissing My feet since I came in. 46 You didn’t anoint My head with olive oil, but she has anointed My feet with fragrant oil. 47 Therefore I tell you, her many sins have been forgiven; that’s why[
a] she loved much. But the one who is forgiven little, loves little.” 48 Then He said to her, “Your sins are forgiven.”
49 Those who were at the table with Him began to say among themselves, “Who is this man who even forgives sins?”
50 And He said to the woman, “Your faith has saved you. Go in peace.”
We speak of her love for Christ, but how much more did he have for her... being unashamed to be seen with her.
