“Wherefore also we pray always for you, that our God would count you worthy of this calling, and fulfil all the good pleasure of his goodness, and the work of faith with power.” (2 Thessalonians 1:11)
When God grants the gift of faith to enable us at the point of salvation (Ephesians 2:8), it isn’t a static power that merely resides in our minds but is rather an empowerment that is expected to grow into a dynamic and demonstrable “divine nature” (2 Peter 1:4).
Faith preserves and protects us.
Jesus insists, “He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life” (John 5:24). These words are precise. Once faith is exercised, an eternal transaction takes place wherein a person is passed from spiritual death to eternal life. This is an absolute change and eliminates the possibility of hell (John 10:28-29).
Faith is power for effective prayer.
The “mustard seed” promise in Matthew 17:20 does not refer to size or amount but to quality. The Greek comparative hoce translated “as” in that passage refers to the same kind of faith as the mustard seed. Just so, the promise of Matthew 7:7 (if you ask and seek, you will find) depends on our confidence (faith) in the heavenly Father.
Faith is the shield against the Enemy.
God’s armor in Ephesians 6:10-18 lists “the shield of faith” that provides an ability “to quench all the fiery darts of the wicked.” That shield is defensive in the sense that it only provides protection when we use it to block the darts. The active use comes when we “resist the devil” (James 4:7) as we remain “stedfast in the faith” (1 Peter 5:9). HMM III
