And Ezra came to Jerusalem in the fifth month, which was in the seventh year of the king. 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 7:8–10, NKJV
If we study God’s Word from cover to cover we will find that only God is perfect. He is Sovereign. He is Holy. He is complete and perfectly righteous. On the other hand, people are none of the above. We are a fallen race who, even after God’s gracious regeneration of our hearts, must continually work out our salvation with fear and trembling.
That implies that we still sin. We still fall into temptation and become entangled. Even when God graciously allows us to walk in victory for awhile, we get our eyes off of Him and on ourselves and begin to believe that we are invulnerable to the worst our flesh can throw at us. That, of course, sets us up for a next stumble.
