Reformed Doctrine teaches that God provides all that we need for salvation.
Reformed Doctrine teaches us about the benefits of belonging to the Lord. We are His people, His sheep. God is our Good Shepherd and will protect us.
As one example, consider Question and Answer 26 of the Heidelberg Catechism.
Question 26. What believest thou when thou sayest, “I believe in God the Father, Almighty, Maker of heaven and earth”?
Answer. That the eternal Father of our Lord Jesus Christ (who of nothing made heaven and earth, with all that is in them; who likewise upholds and governs the same by his eternal counsel and providence) is for the sake of Christ his Son, my God and my Father; on whom I rely so entirely, that I have no doubt, but he will provide me with all things necessary for soul and body: and further, that he will make whatever evils he sends upon me, in this valley of tears turn out to my advantage; for he is able to do it, being Almighty God, and willing, being a faithful Father.
Reformed Doctrine trains our senses to pick out such verses as Verse 4 in today’s Scripture and to remember other verses and Reformed creeds which teach us about God’s protection.
But, with other doctrine, there is no such assurances. Other doctrine falsely teach that Christians can fall from grace and that man’s free-will is the only thing that cause Christians to persevere in their faith. Such believers of this false doctrine may shrink back wondering if they will be so tormented by the events in today’s Scripture.
Reformed Doctrine assures us that “without the will of my heavenly Father, not a hair can fall from my head”.
Consider Question and Answer 1 of the Heidelberg Catechism.
Question 1. What is thy only comfort in life and death?
Answer. That I with body and soul, both in life and death, am not my own, but belong unto my faithful Savior Jesus Christ; who, with his precious blood, hath fully satisfied for all my sins, and delivered me from all the power of the devil; and so preserves me that without the will of my heavenly Father, not a hair can fall from my head; yea, that all things must be subservient to my salvation, and therefore, by his Holy Spirit, he also assures me of eternal life, and makes me sincerely willing and ready, henceforth, to live unto him.
In conclusion, Reformed Doctrine certainly does teach us that we may die and we may suffer. But, we will not experience God’s wrath. Let us generally remember that the events of the Seven Trumpets are a display of God’s wrath. Let us specifically pay close attention to Verse 4: “They were told not to hurt the grass of the earth, nor any green thing, nor any tree, but only the men who do not have the seal of God on their foreheads”. Let us not shrink back.
