The fourth stanza of the hymn “How Firm a Foundation” opens with the words, “When through fiery trials your pathway shall lie, my grace, all-sufficient, shall be your supply” (Trinity Hymnal, revised edition, #94). Is this not the common experience of every follower of Christ? We have trials, and we receive grace. Has the following ever happened to you? You have just woken up in the morning after a good night’s sleep. Then suddenly, evil thoughts have come to you, perhaps even blasphemous or filthy thoughts. You were not thinking about such things. You just woke up, but there they are—horrible thoughts floating around in your mind! And then you might think, “How can I possibly be a Christian and think such things?” My brother or sister in Christ, if that has ever happened to you, do not think it something strange or unusual. A flaming arrow of the evil one has hit you. But what should we do? How can you and I counter that kind of attack? How can we live in the face of such pitiless assaults? The Holy Spirit through the apostle presents us with his way of spiritual warfare. Let us think on God’s word together.
Faith is crucial in spiritual warfare. An ancient soldier without his shield was in deadly danger. The word used for shield in this verse is not the one for the little shield that was also carried by the soldier, but for the large shield that the soldier could hide behind. When carried by many soldiers together, they could form a wall. The shield was often put together in such a way as to make it resistant to attacks by flaming arrows, which were used to wreak havoc and destruction on enemy forces, like later generations would use an artillery barrage or missile attacks.
Faith is the believer’s shield. Faith has three elements: knowledge of the good news (gospel), assent to the good news, and trust or dependence on the good news. The good news points us to the Lord Jesus Christ, who is the object of real saving faith. We do not have faith in faith, but faith in the Lord Jesus (John 3:16). Like the other parts of the armor of God, genuine faith in Christ is a gift of God (Acts 13:48; 16:14; 18:27; Ephesians 2:8-9; Philippians 1:29; 1 Timothy 1:14). Faith leads us away from self-reliance or dependence on money, things, and other people to trust in Christ alone.
Faith has a crucial place in the believer’s life. At the time of salvation, the Holy Spirit presents the ability and sufficiency of Jesus Christ as Savior and God’s promises of eternal life to all who will believe. By the gift of faith, we trust in Jesus the Lord, and entering into union with Christ, we are saved. From that moment on as we trust in the Lord, the Spirit of God strengthens our faith, enabling us to make use of Christ’s fullness as our prophet, priest and king and to participate in every grace and blessing in Christ. We are able to draw strength for him. At the same time the Holy Spirit produces his fruit (Galatians 5:22-23) in us to develop resistance to the fiery darts. As faith unites us to the Savior, so faith receives from the Lord all that we need for our daily walk. We must actively depend on Christ to receive what we need to live for God’s glory and to enjoy the Lord. We must rely on him when we face the attacks of the spiritual forces of evil (Ephesians 6:12).
Grace and peace, David
