Seek first the kingdom of God and his righteousness

Matthew 6:31-33
Therefore do not be anxious, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ For the Gentiles seek after all these things, and your heavenly Father knows that you need them all. But seek first the kingdom of God and his righteousness, and all these things will be added to you.

Philippians 3:14
I press on toward the goal for the prize of the upward call of God in Christ Jesus.

Ephesians 4:28
Let the thief no longer steal, but rather let him labor, doing honest work with his own hands, so that he may have something to share with anyone in need.

Malachi 3:10
Bring the full tithe into the storehouse, that there may be food in my house. And thereby put me to the test, says the Lord of hosts, if I will not open the windows of heaven for you and pour down for you a blessing until there is no more need.

I can personally attest to this! from my own experience 

This is a 100% guarantee from God who created you, takes care of you each day and allows you to take each breath of life.
