The Armor of God
10Finally, be strong in the Lord and in the strength of His might. 11Put on the full armor of God, so that you will be able to stand firm against the schemes of the devil. 12For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places. 13Therefore, take up the full armor of God, so that you will be able to resist on the evil day, and having done everything, to stand firm.
10Finally, my brethren, be strong in the Lord, and in the power of his might. 11Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. 12For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. 13Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.
In this sermon on Ephesians 6:10–13 titled “Exercise,” Dr. Martyn Lloyd-Jones explains the importance of Christians exercising their faith so that they can grow. Christ is the source of strength for a believer. Christians are told to run to Christ for their spiritual food and drink, and yet there must be something more— they must use spiritual food and drink for spiritual development. Christians must exercise their faith so that they can gain the strength needed to stand strong. Dr. Lloyd-Jones gives three practical ways to implement this exercise. First, the Christian must develop a certainty regarding the things of their faith. Second, Christians must exercise their faith by laying hold of the doctrines of Christianity and learn the Bible well so that they can communicate the hope of Christianity to a lost world. Third, they can look to the past and examine the lives of faithful Christians who have walked before in the midst of incredibly trying times. This, says Dr. Lloyd-Jones, serves to encourage, inspire, and strengthen one’s faith. Through Christ, believers can stand strong in the midst of difficult times and this exercise of their faith will only serve to deepen their steadfastness.
Dr. Martyn Lloyd-Jones
Dr. Martyn Lloyd-Jones (1899-1981) was a Welsh evangelical minister who preached and taught in the Reformed tradition. His principal ministry was at Westminster Chapel, in central London, from 1939-1968, where he delivered multi-year expositions on books of the bible such as Romans, Ephesians and the Gospel of John. In addition to the MLJ Trust’s collection of 1,600 of these sermons in audio format, most of these great sermon series are available in book form (including a 14 volume collection of the Romans sermons), as are other series such as "Spiritual Depression", "Studies in the Sermon on the Mount" and "Great Biblical Doctrines". He is considered by many evangelical leaders today to be an authority on biblical truth and the sufficiency of Scripture.
