Back in the day, we had a Vac-U-Form by Mattel. We would take a small square plastic sheet and place it in the Vac-U-Form. After it was heated, we would press it on a desired mold. When the plastic sheet dried, it took on the form of the mold. When we face fires of and pressures in life, we begin to take on the form of our mold. We need to thank the Lord for the heat and pressures we face as they mold us into the image of Christ.
Beloved, do not be surprised at the fiery trial when it comes upon you to test you, as though something strange were happening to you. 1 Peter 4:12
