Where is Your Faith?

Isaiah 7:9 says,"If you are not firm in faith, you will not be firm at all."
Are we trusting God? Do we have faith in God. An old hymn goes like this," Have faith in God, He's on His throne. Have faith in God , He watches o'er His own. He cannot fail, He must prevail; Have faith in God, have faith in God." That is in whom our faith should be centered, focused on. But do we really have faith in God? Certainly, our faith wavers at times but we must always come back to Him. Our faith is just as strong as the One we put our faith in. Is it based on the Almighty God? I know so many married couples who are having troubles now, difficult times. Where is your faith? Is in God or something or someone else? Where is you faith?
