¿Who is our confidence placed on?

Jesus always cared to teach his disciples the true things that were valuable and worthwhile in their lives to free their lives of anxieties and ties.
It is for this reason that we find in this verse the words spoken by Him. "... do not worry about tomorrow ..." Jesus summarizes the theme of absolute devotion to God, and deals with an attitude related to it: be free of anxiety for daily needs.
It refers to the futility of these worries and anxieties, showing that this attitude is not necessary.
He warns that instead of being preoccupied with material things, our interest should be to seek first the kingdom of God and his justice, knowing that in doing so the Lord has offered to faithfully respond to the covenant: All these things will be added to you.

It is important to emphasize that knowing and intimidating with God is our highest priority, no concern should replace that communication and faith in our creator, on the contrary every day we must join efforts and strengthen our relationship of friendship with God in order to bring out in us the true qualities of character that lead us to depend and submit our will to Him.

So, we must not worry about the future, because tomorrow will bring its own eagerness, and surely those who wait on God will see wonders.
