The black seats in my pickup truck do not like the sun (or they love it too much). When they sit in direct sun, they get so hot you can barely sit on them. So, I usually try to park so they don’t get direct sun. And I roll the windows down a little, to let the collecting heat escape. Several days ago, I came out of my office to go home, and my entire front seat was covered in water. During the afternoon, rain deluged my truck, ran through the barely open windows, and splashed all over my seats, dashboard, steering wheel, and doors. For days, my truck smelled musty and wet. Turns out, car windows and doors seal tightly for a reason.
Similar to a car and house, God desires our lives to be sealed up to prevent damaging things from coming inside. Ephesians 4:30 says we are “sealed” in the Holy Spirit (NASB says “by” but the margin notes says “literally ‘in’”). The point is that God does not want us to grieve, or act against, the Holy Spirit, in whom we are sealed. How do we grieve him? The next two verses tell us: “Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice. Be kind to one another, tender-hearted, forgiving each other, just as God in Christ also has forgiven you” (Ephesians 4:31-32). You see, we grieve or disappoint God by letting in things he wants to keep out, like bitterness, wrath, anger, clamor, slander, malice, etc. We decide to crack the window of God’s protection when we pursue a course he has warned us against. The point? Embrace the message the Holy Spirit has given you in the Word of God. Trust those instructions and thereby trust God. Keep your eyes on him, and do what he says. This is how you keep your seal intact.
