Much dreaming and many words are meaningless. Therefore, fear God.
This verse is at the end of the first "section" of chapter 5, in my translation. The section is subtitled: Fulfill Your Vow to God. This lends a little to my understanding today. The writer urges us to keep our promises and our vows to God realistic, and at a reasonable level. We should not make promises to God based on "much dreaming" and then have to take back the promise later. This is kind of a rough message, because we all fail, continue to slip up and sin, and fall short of our goals in terms of being like Jesus. But the message for me is to keep God near, make goals with God's guidance, and refrain from promising perfection or an outcome I know is not attainable.
Holy Father, you know me better than I know myself. Help me to set goals which will lead to growth and holiness, and not to frustration and disappointment. I am far from perfect, and know I will never be perfect. You are transforming me each day, and I am moving in the right direction. Amen
