But when you ask him, be sure that your faith is in God alone. Do not waver, for a person with divided loyalty is as unsettled as a wave of the sea that is blown and tossed by the wind. Such people should not expect to receive anything from the Lord. Their loyalty is divided between God and the world, and they are unstable in everything they do. (James 1:6-8 NLT)
If you have ever seen the constant rolling of huge waves at sea, you know how restless they are-subject to the forces of wind, gravity, and tide. Doubt leaves a person as unsettled as the restless waves. If you want to stop being tossed about, rely on God to show you what is best for you. Ask him for wisdom, and trust that he will give it to you. Then your decisions will be sure and solid.
