Casting lots
Can Christians "cast lots" or flip a coin to determine the will of God or what God wants us to do? Proverbs 16:33 and Acts 1:23-26 seem to speak favorably of this. However, would such a practice be "putting the Lord your God to the test"?
In Leviticus 16:8 God gave Moses instructions on how the high priest was to cast lots to identify the scapegoat sent into the desert on the great Day of Atonement. Beyond that, there are relatively few instances in the Bible of people casting lots. Those instances relate what people did; they do not carry with them the command to do likewise. In addition, God has not promised to reveal his will through that practice.
God has revealed his will to us in the pages of the Bible. He gives us freedom to make decisions in life that concern our earthly lives. When we prayerfully consider what decisions will glorify God and reflect his revealed will in Scripture, we can choose courses of action with Christian confidence and contentment.
