Study the covenant of grace. The first rule for relieving slavish fear is to consider seriously and study thoroughly the covenant of grace in which all believers stand. A clear understanding of the covenant’s nature, extent, and stability, along with our interest in it, will go a long way to cure our sinful and slavish fear. A covenant is more than a naked promise. In the covenant, God has graciously considered our fears, doubts, and weaknesses; therefore, he proceeds with us in the highest way of solemnity, confirming his promises by way of an oath (Hebrews 6: 13, 17) and a seal (Romans 6:11). He places himself under the most solemn ties and engagements to his people so that we might take strong comfort from so firm a ratification of the covenant (Hebrews 6:18). He has ordered it so that it might afford strong support and encouragement to our faint and fearful spirits in the midst of trouble from within and without. In the covenant, God gives himself to his people to be their God (Jeremiah 31:33; Hebrews 8:10). He bestows himself upon us in all his glorious and essential properties so that we are assured that (in all fears and hardships) he will faithfully perform whatever his almighty power, infinite wisdom, and incomprehensible mercy can afford for our protection, support, deliverance, direction, pardon, or refreshment. God expects us to improve this by faith as the most sovereign antidote against all our fears in this world. “But now thus saith the LORD, that created thee, O Jacob, and he that formed thee, O Israel: “Fear not: for I have redeemed thee, I have called thee by thy name, thou art mine. When thou passest through the waters, I will be with thee” (Isaiah 43:1-2). “Fear thou not, for I am with thee, be not dismayed, for I am thy God” (Isaiah 41:10).
