"Then I said, 'Ah Lord God! Behold I do not know how to speak, for I am only a youth.' But the Lord said to me, 'Do not say "I am only a youth" for to all to whom I send you, you shall go, and whatever I command you, you shall speak. Do not be afraid of them, for I am with you to deliver you,' declares the Lord." --Jeremiah 1:6-8In this passage God commands Jeremiah to speak to the people on His behalf and what does Jeremiah do? "I do not know how to speak, for I am only a youth." This wasn't an easy task, nor would it be a fun task, or a task where the people would love him, it was a difficult, uncomfortable hard task. Jeremiah thought himself too young. Jeremiah didn't think that God could use him because of his age. But what does God say? That HE would be with Jeremiah, give him the words to say, and deliver him. God doesn't just command him to do something, he also gives us promises to go with that command.
How often are we commanded to do something, and we instead think of excuses - "I'm too busy!", "I'm too young!", "Too hard!", "I don't have the resources", etc...? Do you put yourself in a box because of your age or your personality or your resources or your strength/energy? This life wasn't meant for our comfort. This life wasn't meant for our ease. This life wasn't meant for our enjoyment. This life was given to us to prepare for eternity. It was given to us to glorify God and serve Him and love Him with everything in us. We aren't our own, we have been bought with a price (1 Cor 6:19-20). We were created to for God's glory, and we are here to glorify Him with everything we do and say and think.
Remember that our God is the God of impossibilities. He can anything and everything He wants. Nothing is too big for Him, and with God on our side, we can do all things because He gives us His strength. In our weakness, His strength is perfected. In our failures, He wisdom is shown. He doesn't give us hard commands and then leaves us, He goes with us every step. So press on, fellow soldiers. Don't give up. Face the next temptation in God's strength, relying on His promises. Fight the next battle in God's strength, relying on His promises. Confront the next impossibility in God's strength, relying on His promises.
