For sake of full disclosure, I have never died before, but I have observed the process many times. We may get close and cheat death a couple of times, but even that experience wouldn’t necessarily give you insight helpful to all.
So for what it is worth, this is how I would recommend approaching your impending death, based on the Bible and observation. The first thing I encourage is for you to talk about dying, if you can. People try to avoid the subject at all costs. This is foolish, we all have to die and most likely will all mourn. What should you talk about?
Mend Fences if Possible If there are hard feelings or misunderstandings between you and anyone, take the initiative to talk, forgive and repent. Don’t let pride or stubbornness ruin this for you. If you must agree to disagree, then do so peaceably.
Express Your Love Some of us are not good at stating our love for others. People need to hear this in words. Say it. It will mean much to those who will mourn your passing.
Don’t Extract Promises Guilt trips should not be your legacy. You may express desires, but don’t twist arms, issue threats or have others make vows that they may not be able to keep.
Share Your Fears Are you afraid of death or the process of dying? Tell somebody. There is no shame in this and it will help. You don’t have to tell everybody, but share with someone you trust.
Express Your Confidence Has God given you a strong faith in Jesus’ saving power? Then make sure that everybody knows. Be gentle, they may not be at the same place spiritually, but this is your last chance at making a strong witness to people who really matter to you. Consider even writing a witness to be read at your funeral or doing a video to be shown there.
Support Those Who Are Taking It Hard Hopefully, people will miss you. Express your confidence in their ability to carry on. Remind them of the promise of eternal life and emphasize that you can be together again in Heaven.
Beyond talking to others, make prayer a vital part of your dying process. Jesus died for your sins so that you can be with Him. That relationship is about to take a big step, so anticipate that step by praising God, thanking God for things in your life, confessing your sins and asking for His intercession in situations you will leave behind.
If you do struggle physically in the last days or hours, don’t be surprised or interpret the situation as God’s punishment. Death is the result of sin. It isn’t meant to be easy, but because of grace, it is only temporary. God can bring you safely home.
