The true Christian is called to be a soldier and must behave as such from the day of his conversion to the day of his death. He is not meant to live a life of religious ease, indolence and security. He must never imagine for a moment that he can sleep and doze along the way to heaven, like one traveling in an easy carriage.
Sanctification is the outcome and inseparable consequence of regeneration. He who is born again and made a new creature receives a new nature and a new principle and always lives a new life.
Sanctification is that inward spiritual work which the Lord Jesus Christ works in a man by the Holy Spirit when He calls him to be a true believer. He not only washes him from his sins in His own blood, but He also separates him from his natural love of sin and the world, puts a new principle in his heart and makes him practically godly in life.
Necessity is laid upon us. We must fight. There are no promises in the Lord Jesus Christ's epistles to the seven churches, except to those who 'overcome.' Where there is grace, there will be conflict. The believer is a soldier. There is no holiness without a warfare. Saved souls will always be found to have fought a fight.
The 'means of grace' are such as Bible reading, private prayer, and regularly worshiping God in Church, wherein one hears the Word taught and participates in the Lord's Supper. I lay it down as a simple matter of fact that no one who is careless about such things must ever expect to make much progress in sanctification.
