From Luke 10. A certain man left Jerusalem and went down to Jericho. The certain man is Jesus. None showed mercy but the good Samaritan. Who is the good Samaritan?
Deut 7:9 Know therefore that the LORD thy God, he is God, the faithful God, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations.
Who only fulfilled the law? Christ Jesus
This is a story of the Father and the Son.
