A good study to make on your own has to do with a little phrase, “the good hand of his God upon me” found in the stories of Ezra and Nehemiah.
On the first day of the first month he began his journey from Babylon, and on the first day of the fifth month he came to Jerusalem, according to the good hand of his God upon him. For Ezra had prepared his heart to seek the Law of the Lord, and to do it, and to teach statutes and ordinances in Israel. (Ezra 7:9-10)
“Then, by the good hand of our God upon us, they brought us a man of understanding.” (8:18)
Then I proclaimed a fast there at the river of Ahava, that we might humble ourselves before our God, to seek from Him the right way for us and our little ones and all our possessions. For I was ashamed to request of the king an escort of soldiers and horsemen to help us against the enemy on the road, because we had spoken to the king, saying, “The hand of our God is upon all those for good who seek Him, but His power and His wrath are against all those who forsake Him.” So we fasted and entreated our God for this, and He answered our prayer. (vv. 21-23)
Furthermore I said to the king, “If it pleases the king, let letters be given to me for the governors of the region beyond the River, that they must permit me to pass through till I come to Judah, and a letter to Asaph the keeper of the king 's forest, that he must give me timber to make beams for the gates of the citadel which pertains to the temple, for the city wall, and for the house that I will occupy.” And the king granted them to me according to the good hand of my God upon me. (Nehemiah 2:7-8)
Then I said to them, “You see the distress that we are in, how Jerusalem lies waste, and its gates are burned with fire. Come and let us build the wall of Jerusalem, that we may no longer be a reproach.” (v. 17)
And I told them of the hand of my God which had been good upon me, and also of the king’s words that he had spoken to me. So they said, “Let us rise up and build.” Then they set their hands to this good work. (v. 18)
When I first began to travel overseas, especially to some really risky places, this concept of His good hand being upon me, became dear to my heart. It helped offset some of the fears I faced.
