What does the Bible say about God’s leading? It says that if we acknowledge God in all our ways, He will direct our paths (Prov. 3:5–6). We are encouraged by Scripture to learn the will of God for our lives, and we do so by focusing our attention not on the decretive will of God but on the preceptive will of God. If you want to know God’s will for your life, the Bible tells you: “This is the will of God, your sanctification” (1 Thess. 4:3). So when people wonder whether to take a job in Cleveland or in San Francisco, or whether to marry Jane or Martha, they should study closely the preceptive will of God. They should study the law of God to learn the principles by which they are to live their lives from day to day.
