Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. (Ephesians 6:16)

Faith is  a shield that you may use for warding off every kind of arrow, yea, even the fiery darts of the enemy.

For this shield cannot be penetrated even by javelins of fire. You cannot be cast into a condition in which faith shall not help you.

There is a promise of God suitable for every state, and God has wisdom and skill and love and faithfulness to deliver you out of every possible jeopardy.

And therefore you have only to confide in God, and deliverance is sure to come. Even when your trouble has been brought upon you by your own fault, faith is still available.

When your affliction is evidently a chastisement for grievous transgression, still trust in the Lord. The Lord Jesus prayed for erring Peter Peter that his faith might not fail him.

His hope of recovery lay there. When you have stepped aside and when at last the heavenly Father makes you smart under his rod—to cast yourself upon him then is faith indeed.

If any of you at this time are in great distress and are conscious that you richly deserve all your troubles because of your folly, still trust in the mercy of the Lord.

Do not doubt the Lord your Savior, for he invites his backsliding children to return unto him. ((Charles SpurgeonAt the Master’s Feet [Grand Rapids: Zondervan, 2005], December 7.))
