To me Gideon's heart was set on not letting the enemy have his wheat. He took all the necessary measures to make sure that they would not get it and his family would! He was risking losing it all, but here he was working away when the angel found him and hailed him a mighty man of valor. Notice that Gideon didn't take issue with whether he was a couragous warrior or not, but began asking where God was.
What the angel said to him has given me much to think about. In response to Gideon's question if God is with us why has all this happened? The angel said - go in this your strength. Gideon's intense quest for God was actually his strength. When we continue to seek the Lord even in adversity - our strength really develops.
Isaiah 55 says seek the Lord while He may be found; call on Him while He is near. As we continue seeking Him our strength will continue to increase. He is not challenged by our questions and He never loses heart or says a question is too difficult for Him to take on. He won't wring His hands in dispair wondering what He's going to do with our sincere questions. And as we seek Him - we will grow in Him.
If you are a caregiver - and you are still seeking Him - you won! You didn't give up - you are a mighty man (or woman) of valor who is determined to not let the enemy have your stuff (or faith). So don't stop now - keep seeking the Lord as He truly is our strength.
