Faith is essentially trusting God's word and his promises. When we truly believe God and His promises it helps us make wise decisions in our life. Faith causes us to seek God's guidance before we make important decisions in our lives.
We live in a society where one in two marriages end in divorce. Many say that it is because divorce is too easy. I think maybe it is because too many enter into marriage without ever seeking God's counsel. Many people spend more time making a decision about buying an automobile than they do in picking a person to spend the rest of their lives with.
We should exercise our faith in God when we make any important decision. Will the outcome glorify God? Is what we want to do in harmony with God's Word? How will what I do effect my testimony? Will my decision draw me closer to God or lead me farther away?
Those are all questions we need to ask, having faith that the decisions God would have us make are the wisest ones. Make wise decisions by having faith in a God who loves you and wants the very best for you.
