"For Ezra had set his heart to study the law of the LORD and to practice it, and to teach His statutes and ordinances in Israel" (Ezra 7:10, NASB).
The Bible tells us that Ezra's trip from Babylon to Jerusalem, a journey of about 900 miles, took less than five months because "the gracious hand of his God was on him." And then adds, "This was because Ezra had determined to study and obey the Law of the LORD and to teach those decrees and regulations to the people of Israel" (Ezra 7:9-10).
When we set our hearts upon studying and obeying God's Word, and add the desire to teach it to others -- God will prosper our steps with expedience and favor. "The path of the righteous is like the light of day, shining brighter and brighter" (Proverbs 4:18).
Ezra and his fellow footmen were protected from attacks by bandits, and were preserved in their supplies, both physically and emotionally. They left Babylon in high hopes, and arrived in Jerusalem refreshed and filled with wonder.
Elsewhere the Bible says, "Great peace have they who love Your Law; and nothing will offend them" (Psa.119:165). Set your heart upon God's Word, and watch how God begins to prosper your way; how He blesses you in business, in friendships, in breakthroughs, and in favor with others.
The bottom line is that God's Word is true and trustworthy, and by opening our hearts to its life-giving power, we can live everyday in the deep assurance that God will open His heart to us with blessing and favor.
