Jesus knew this world would challenge our faith so He gave us instructions for how we can prevent ourselves from worrying. We don’t have to worry about anything that might happen in this life because our Heavenly Father is taking care of us.
If God takes care of the birds of the air He will surely take care of us. The vast majority of our worries never come true. The rest are going to happen no matter how much time we spend in worry.
We must fortify our faith to prevent fear doubt and anxiety from developing in our hearts. And we need to focus upon only the concerns that must be addressed today.
