If you had thought you were now too old to achieve your dreams, and that your time has passed, don't give up. All you need do is to "Seek the LORD and his strength, seek his face continually" (1 Chronicles 16:11). There's a material that can change the oldest of men; it's the Word of God! Moses answered the call of God at the age of eighty. His old age didn't truncate his destiny. It was the same with Abraham, who received the promise at seventy-five years of age.
The Bible says, "But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint" (Isaiah 40:31). The energy you require for all that God has destined you for is of the Spirit, and it's inherent in you: "That energy is God's energy, an energy deep within you, God himself willing and working at what will give him the most pleasure" (Philippians 2:13 MSG). It's not too late to live for the Lord, and glorify Him with your life.
