But seek first the kingdom of God and his righteousness, and all these things will be added to you. “Therefore do not be anxious about tomorrow, for tomorrow will be anxious for itself. Sufficient for the day is its own trouble." (Matthew 6:33-34 ESV)
Jesus proves His power to provide in dramatic ways throughout the New Testament. Indeed His first miracle was to turn water into wine. Tim Keller reminds us that it is the 'master of the feast's' responsibility to make sure the guests are provided for. In Jesus intervention and provision here He gives us a hint that under His Lordship He will not be caught short in providing for His guests.
Another dramatic example is that of the feeding of the five thousand [just read it] with miraculous provision and with so much left over He seems to indicate that not only can He provide for our needs, but there's plenty more for those who weren't there. Greatest of all is His provision of a way in which we can be reconciled to God; through His offering up of Himself as a propitiation for our sins.
Let's remember that "He gives us life and breath and all things" and it is "in Him we live and move and have our being" (Acts 17:25&28). With all this, and a lot more, in mind; let's give thanks to the One "who is able to do far more abundantly than all that we ask or think".
