Grieve Not

Eph. 4:30
And grieve not the Holy Spirit of God, whereby ye are sealed unto the day of redemption.
Distressing, or causing  the Holy Spirit to be sad happens when we do something or say something that is contrary to the nature of God. Our renewed vessel was made to bring honor to His Name. When we say things that hurt or demean others, we grieve the Holy Spirit. When we allow bitterness, anger, and evil speaking to dwell in our vessel of clay, the Holy Spirit will not abide. He will depart from us if we don’t take action. It is true that a vessel that is fully consecrated and sanctified to God will be sensitive to the checks of the Holy Spirit, and will guard against things that will grieve Him. But Satan is out to destroy what God has made new, and will bring temptations that will play with our emotions and humanity. We are still human, and subject to the temptations of the flesh. We are admonished to put off any behavior or actions that would cause the Holy Spirit to depart. God will never leave us or forsake us, but His Spirit cannot abide where sin abides. He will continue to deal with us and call us back to Him.

Put Off and Put On

Eph 4:22

Regarding your previous way of life, you put off your old self [completely discard your former nature], which is being corrupted through deceitful desires.... and put on the new self [the regenerated and renewed nature]..

The way we lived before coming to Christ will look different for everyone. Before Christ, we looked at life through a different lens. In our sinful state, we were focused on our own desires and contentment. For some, it may have been the pursuit of a career and financial security. Others focus on personal and social relationships, and there were those who looked for contentment by partaking of the pleasures of sin. But we have come face to face with Christ, and our way of life has changed. The looking glass of life has been renewed and we now see life through the eyes of Christ. Life takes on a new perspective, we may still desire to have career goals, social relationships, and even some of the pleasures of life that God has blessed us with.  But we now seek to please our Creator in everything we do. Christ is the center of our life and through the help of the Holy Spirit, we put on behaviors that will please Him.
