"So take diligent heed to yourselves to love the LORD your God. For if you ever go back and cling to the rest of these nations, these which remain among you, and intermarry with them, so that you associate with them and they with you…" or you are in really big trouble!
Joshua was very old and ready to die. His last words were about love! Be careful whom you love! Be careful to whom you give your heart.
Be careful to love God first. If the Lord is your Savior, He also is your first love. He is your first love before you are married. He is your first love when you are married. He is your first love after your marriage. The love of God for you began before your were born and continues after you die. Love God, because God's love is eternal.
Be careful to love a boy or girl who loves the Lord like you do. Don't intermarry, don't give your heart, don't love anyone who does not love the Lord like you! God's love will make your marriage work. It is not enough to marry a Christian. Marry someone who loves God first, or your husband or wife will steal your heart away from God. Then they will break your stolen heart into a million pieces.
Joshua's dying words are be careful about love.
For me to live is Christ.
