And he said to them, “Truly, I say to you, there are some standing here who will not taste death until they see the kingdom of God after it has come with power.” – Mark 9:1
Then I turned to see the voice that was speaking to me, and on turning I saw seven golden lampstands, 13 and in the midst of the lampstands one like a son of man, clothed with a long robe and with a golden sash around his chest. 14 The hairs of his head were white, like white wool, like snow. His eyes were like a flame of fire, 15 his feet were like burnished bronze, refined in a furnace, and his voice was like the roar of many waters. – Revelation 1:12-15 (ESV)
“Remember the law of my servant Moses, the statutes and rules that I commanded him at Horeb for all Israel. “Behold, I will send you Elijah the prophet before the great and awesome day of the Lord comes. – Malachi 4:4-5 (ESV)
Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. – Romans 12:2 (ESV)
And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another. – 2 Corinthians 3:18 (ESV)
And he began to teach them that the Son of Man must suffer many things and be rejected by the elders and the chief priests and the scribes and be killed, and after three days rise again. 32 And he said this plainly. – Mark 8:31
the cross and resurrection are the only vantage point from which Jesus’ life and ministry can be understood according to their divine purpose, and that until the cross and resurrection all other knowledge of Jesus is inadequate and peripheral. The command to silence is especially pertinent in the afterglow of the transfiguration, lest the disciples succumb to the glory and emotional adrenaline of the mountain rather than the necessity of the way to Jerusalem and the cross. The transfiguration is indeed a preview of the resurrection, but the disciples inherit the gloria resurrectionis only through the via dolorosa crucis. – James Edwards
So we do not lose heart. Though our outer self is wasting away, our inner self is being renewed day by day. 17 For this light momentary affliction is preparing for us an eternal weight of glory beyond all comparison, 18 as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal. – 2 Corinthians 4:16-18 (ESV)
Not only is all your affliction momentary, not only is all your affliction light in comparison to eternity and the glory there. But all of it is totally meaningful. Every millisecond of your pain, from the fallen nature or fallen man, every millisecond of your misery in the path of obedience is producing a peculiar glory you will get because of that.
I don’t care if it was cancer or criticism. I don’t care if it was slander or sickness. It wasn’t meaningless. It’s doing something! It’s not meaningless. Of course you can’t see what it’s doing. Don’t look to what is seen.
When your mom dies, when your kid dies, when you’ve got cancer at 40, when a car careens into the sidewalk and takes her out, don’t say, “That’s meaningless!” It’s not. It’s working for you an eternal weight of glory.
Therefore, therefore, do not lose heart. But take these truths and day by day focus on them. Preach them to yourself every morning. Get alone with God and preach his word into your mind until your heart sings with confidence that you are new and cared for.
