Romans 14:23
But the man who has doubts is condemned if he eats, because his eating is not from faith; and everything that does not come from faith is sin.
Luke 12:27-31
"Consider how the lilies grow. They do not labor or spin. Yet I tell you, not even Solomon in all his splendor was dressed like one of these. If that is how God clothes the grass of the field, which is here today, and tomorrow is thrown into the fire, how much more will he clothe you, O you of little faith! And do not set your heart on what you will eat or drink; do not worry about it. For the pagan world runs after all such things, and your Father knows that you need them. But seek his kingdom, and these things will be given to you as well.
Matthew 13:22
The one who received the seed that fell among the thorns is the man who hears the word, but the worries of this life and the deceitfulness of wealth choke it, making it unfruitful.
Philippians 4:6-7
Do not be anxious about anything, but in everything, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.
1 Peter 5:7
Cast all your anxiety on him because he cares for you.
