"Too much activity gives you restless dreams; too many words make you a fool."Ecclesiastes 5:3 (NLT)
"For the fool speaks folly, his mind is busy with evil." Isaiah 32:6 (NIV)
"But Martha [overly occupied and too busy] was distracted with much serving; and she came up to Him and said, Lord, is it nothing to You that my sister has left me to serve alone? Tell her then to help me [to lend a hand and do her part along with me]!" Luke 10:40 (Amplified Bible)
"Too much," "busy with evil," and "too busy" all seem to yield poor results.
But what about these verses?
"Plant your seed in the morning and keep busy all afternoon, for you don’t know if profit will come from one activity or another—or maybe both." Ecclesiastes 11:6 (NLT)
"Likewise, teach the older women to be reverent in the way they live, not to be slanderers or addicted to much wine, but to teach what is good. Then they can train the younger women to love their husbands and children, to be self-controlled and pure, to be busy at home, to be kind, and to be subject to their husbands, so that no one will malign the word of God." Titus 2:3-5 (NIV)
These verses indicate being busy is good. However the individuals are to be busy doing their work, that is making a living and keeping their house. I think this last verse sums it up.
"We hear that some among you are idle. They are not busy; they are busybodies." 2 Thess 3:11 (NIV)
Being busy is good, if you are busy at the right things. Doing God's work, making a living for your family and keeping your home for your family. We are not called to be idle or lazy. However, we are also not called to be overly busy, which often results in neglected our family, and neglecting God. (Too busy to pray?) We aren't to be minding everyone else's business at the expense of our own.
As a mom, I feel very busy keeping up with housework and children's activities. But I know I am doing the work that God prepared in advance for me to do. Wisdom comes in knowing what to say "no" to, so that we don't become overly busy.
It is important to take on and complete the work that God prepared in advance for us to do*. Be discerning. Remember, just because it is a "good" thing to do, doesn't mean it is a "God" thing to do. Be busy working for God, but don't take on any side jobs from the devil.
*Ephesians 2:10 -- For we are God's workmanship, created in Christ Jesus to do good works, which God prepared in advance for us to do.
