We can't control many aspects of our lives (and satan knows it). The enemy will use everything, and everyone, around us to get is off track and steer us from God's light (if even for a day).
Don't fall for it. Many times the devil will manipulate the people closest to us in order get a "rise" out of us, so then we'll spend the rest of the day in anger or worry. When you're feeling under attack, recognize it for what it is.
What should we do? Stop worrying over those you have no control over and spend some time in the Good Book, as it's said, "Worry weighs a person down; an encouraging word cheers a person up." (Proverbs 12:25) Also, turn those persistent worries over to God, "Give all your worries and cares to God, for he cares about you." (1 Peter 5:7) And then pray, "Don't worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done." (Philippians 4:6)
By doing these things, we are calling on the power of God to aid in our fight against satan and his schemes. When we first seek the kingdom of God, all else will be given to us (Matthew 6:33) So, don't keep God on the bench in your fights with the enemy.
"Always be joyful. Never stop praying and give thanks in all circumstances; for this is God's will for you in Christ Jesus." (1 Thessalonians 5:16-18)
