To keep God first, we must confront and overcome worry that distracts us from trusting Him. Jesus is saying:
Matthew 6:33
I understand your struggles, your challenges and your needs. I know you require food, clothing, shelter and other daily necessities... But the key is this: Seek first the Kingdom of God and His righteousness... Put Me first, and will take care of the rest.
What more reassurance could we ask for than these gracious words from Jesus? When we trust Him with our needs, we can live one day at a time without being crushed.
