“be filled with the Spirit” (Ephesians 5:18) is to be controlled by the Holy Spirit. This is a present continuous action and requires a believer to be (a) daily yielded to God, (b) daily in repentance with confession with godly sorrow, (c) daily allowing the word of God to richly indwell the inner man. Being controlled by the Holy Spirit empowers a believer (a) daily in spiritual battle (Spirit versus flesh) and, (b) daily in living out the person and character and conduct of Christ and in being obedient to the will of God.
A True Disciple is Saved and Surrendered
The first mark of a true disciple is that he is saved. Jesus said there are many people doing religious things in His name, yet they will be turned away from heaven because they were never really born again. But salvation is just the first step. Once we’re saved, we cannot continue to run our own lives. We must turn over the throne of our heart to Him, surrendering everything to His leadership. It is difficult to give up control, but the truth is, our lives will never make sense or be fulfilling until the One who made us is completely in charge.
