"Be of good courage, and he shall strengthen your heart, all ye that hope in the LORD" (Psalm 31:24).
Let's face the facts. There are some people who shouldn't homeschool their children. For whatever reason, they lack the resources or ability to teach, and their children would do better in a conventional school setting. However, there is another side to the coin. Many parents who should be schooling their children at home are not. Responding in fearful apprehension, they use the excuse, "It's great others can homeschool, but I could never do that!" The status quo or their own inhibitions have convinced them of failure while God waits for them to believe in His wisdom and guidance for success.
Many great leaders in the Bible faced similar initial fears. Moses, Joshua, and Gideon all experienced anxiety and thought, "This job is too big for me." Afraid to try and wanting to quit before they even started, God challenged them to reach out and trust Him for courage and strength. God graciously gave Moses a spokesperson in Aaron, Joshua was given encouragement at Jericho by God's holy messenger, and Gideon received confirmation of his call through a fleece that was both wet and dry. Stepping out from behind their fearful excuses, they were used greatly by God to accomplish His will.
What task has God set before you that you're afraid to attempt? In addition to homeschooling, is He asking you to work with the church youth group, serve in a short-term mission, or start a Bible study in your home? Whatever His leading might be, don't let fear stop you from stepping out in faith. God is mighty, and He will go before you and help you accomplish great things for His glory. "Call unto me, and I will answer thee, and shew thee great and mighty things, which thou knowest not" (Jeremiah 33:3).
Lord, forgive me for being afraid to follow You. Sometimes what You ask seems too big for me to accomplish. Use me for Your glory and strengthen me now to follow You in obedience. In Jesus' name, Amen.
