Ephesians 4:30 “And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.”
The verse above is not a suggestion to the believer but a command. God commands the believer not to grieve His Holy Spirit. There is a reason why God does not want you to grieve His Holy Spirit, and that reason is because of the work that He does in your life. When you grieve the Holy Spirit, you are grieving Him to your own detriment. Let me show you the works of the Holy Spirit in your life.
First, the Holy Spirit seals your salvation. The verse above reminds us that we are sealed by the Holy Spirit. This does not mean that if you grieve Him that you will lose your salvation; rather, it means you should do everything in your power to be sure to allow Him to work in your life because of what He has done in your life by securing your salvation.
Second, the Holy Spirit strengthens you. Ephesians 3:16 shows us that the believer is “strengthened with might by his Spirit.” In other words, you will not have the strength to do the Lord’s work without the help of the Holy Spirit. You can try to do the work of the Lord in your own power, but you will quickly run out of strength. It is the Holy Spirit who gives you the power you need to do the Lord’s work successfully.
Third, the Holy Spirit helps you to pray. Ephesians 6:18 says, “Praying always with all prayer and supplication in the Spirit,…” You will find that the Holy Spirit is the one who guides you to pray as you ought. Romans 8:26 says, “Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.” Your prayer life will never be what it should be without the Holy Spirit guiding you as you pray. If you find your prayer life is waning, you would be wise to ask the Holy Spirit to help you when you pray. You will be much more successful in your prayer life when you allow the Holy Spirit to guide you.
Fourth, you are built by the Spirit. Ephesians 2:22 teaches that the Holy Spirit builds the believer. The need for the Holy Spirit in your life is critical to you becoming the believer that God wants you to be. Now, His building of your life may not always be easy, but He knows what He is doing in your life, and part of His building is to send you through hard times. The Holy Spirit will never fail to make you into the image of Christ if you will allow Him to do His work through you.
Fifth, you are to be filled with the Spirit. Ephesians 5:18 commands the believer to be filled with the Spirit. It is much better to be filled with the Spirit so that He can work through you than to be filled with your own agenda and fleshly whims. To be filled with the Spirit means that you are empty of yourself and that He is in total control of ALL that you do.
My friend, the reason you don't want to grieve the Holy Spirit is because you will hinder His ability to do these works through your life. When you grieve the Holy Spirit, you are hindering His ability to strengthen you, help you pray, build you, and fill you. Let me ask you, are you grieving the Holy Spirit with your spirit of bitterness, and wrath, and anger, and clamour, and evil speaking, and malice? If you are grieving Him, you are doing so to your own detriment. Instead of grieving the Spirit, it would be better to yield to Him so that He can do His complete work through your life.
