“When Abram was ninety-nine years old, the LORD appeared to Abram and said to him, “I am Almighty God; walk before Me and be blameless.” (Gen. 17:1)
The great power of God was on display during creation week. The ability to speak all into existence is power man does not have, but God does. What is impossible with man is possible with God (Luke 18:27). In fact, all things that are possible and compatible with His nature, are possible with God (Matt. 19:26; cf. Titus 1:2). Abraham and Sarah learned this great lesson with the birth of Isaac, though Sarah was past the age of childbearing (Gen. 16:1-2, 18:11; cf. Heb. 11:11). Nothing is too hard for the LORD (Gen. 18:14).
Man is rather feeble, yet he thinks himself to be something from time to time. Man does not have the power to retain his spirit at death, yet God will raise him up at the last day (Ecc. 8:8; John 5:28-29, 6:39-40). Man can (and does) write many books, but only God’s book will endure forever (Ecc. 12:12; 1 Pet. 1:24-25). Man can produce false systems of salvation, but only the gospel has the power to save (Acts 5:33-39; Rom. 1:16). Man can claim to be his own savior, but only Jesus of Nazareth was approved by the power of God as our Savior (Acts 2:22-40, 4:10-12).
Let us bow before the Almighty God knowing that when we are weak, then we are strong in Him (cf. 2 Cor. 12:9-10).
