We should always ask God for guidance in decision-making.  No situation is too trivial.  The Lord has been generous, kind and eager to rightly-direct both good and evil people. Additionally, faith-filled Bible study is critical to developing our decision-making skills.  Without the Word of God firmly planted in our hearts, we live in peril, often making costly or even deadly mistakes.  Our Heavenly Father wishes for us to mature in His wisdom so that we become an enormous blessing to others.
