"Only be strong and very courageous, that you may observe to do according to all the law which Moses My servant commanded you, do not turn from it to the right hand or to the left, that you may prosper wherever you go." Joshua 1.7The faith of the heart is always aware of the circumstances. It does not take one step without considering the heart's feelings.
Contrary to feelings, we have faith with reason, which does not waste time with what the eyes see. It does not look to right or to the left, nor does it look back.
Instead, it looks ahead, firm in the Promises of the Author and Finisher of Faith.
