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.
The Christian can struggle with assurance of salvation, feel tormented by past sins, or disbelieve that they could truly be saved. In this sermon focused on Ephesians 6:10–13 titled “Attacks on Assurance (1),” Dr. Martyn Lloyd-Jones diagnoses the real cause of struggles with assurance. Often the devil causes the Christian to question whether anyone can be sure of their salvation or he makes them feel presumptuous to be so certain of their salvation. The truth is that only the devil makes one look back at sin—Christ makes them look back to His work on the cross. That is where the Christian must place their confidence. God commands His people to be certain of their salvation and to know the truth that they are saved as seen in 1 John 5. Christians are encouraged to not be so busied with the state of their spiritual health that they make themselves ill but instead lay hold of the promise of salvation and rest in Christ.
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.
