He Himself has said, “I will never leave you nor forsake you.” So we may boldly say: “The Lord is my helper; I will not fear. What can man do to me?” (Hebrews 13:5-6)
Another acceptable category of promises to God involves those based on His promises to us. God has already promised to be with us every step of our pilgrimage here on earth. “I will never leave you nor forsake you.” Consequently, we can declare with great confidence: “The Lord is my helper; I will not fear. What can man do to me?”
The Lord knows our vulnerability to fear, such as the fear of man. “The fear of man brings a snare” (Proverbs 29:25a). Many traps and entanglements await those who are afraid of man’s opinions or actions. Abraham jeopardized his own wife, because he was afraid of the Egyptians. “Therefore it will happen, when the Egyptians see you, that they will say, ‘This is his wife’; and they will kill me, but they will let you live. Please say you are my sister, that it may be well with me for your sake, and that I may live because of you” (Genesis 12:12-13). King Saul sinned against God, because he feared the people. “Then Saul said to Samuel, ‘I have sinned, for I have transgressed the commandment of the LORD and your words, because I feared the people and obeyed their voice'” (1 Samuel 15:24). Of course, God’s protection against such snares is to depend upon Him, when we are tempted to fear man. “The fear of man brings a snare, but whoever trusts in the LORD shall be safe” (Proverbs 29:25).
The Lord has given many promises of His presence with His people to protect them from man. To Joshua, God promised: “No man shall be able to stand before you all the days of your life; as I was with Moses, so I will be with you. I will not leave you nor forsake you” (Joshua 1:5). To Paul, the Lord promised: “Do not be afraid, but speak, and do not keep silent; for I am with you, and no one will attack you to hurt you; for I have many people in this city” (Acts 18:9-10). To every believer in Christ, He has promised: “Lo, I am with you always, even to the end of the age” (Matthew 28:20). Therefore, “we may boldly say: ‘The Lord is my helper; I will not fear. What can man do to me?'”
When our promises are based on the promises of God, His faithfulness and His ability become the validation of our promises.
