Humility is like a magnet that attracts favor, attracts blessing. The more humble you become, the more magnetic you become! A humble spirit attracts honor, attracts favor, attracts blessing. A prideful spirit repels it.
When you humble yourself, the Holy Spirit does the heavy lifting. Humility allows God to do what God does. Humility is the key to spiritual authority: more humility = more authority.

If you want to see God move in powerful ways, all you need to do is stay out of God’s way. How? Humility! Staying on your knees is the way to stay out of the way! Or to say it another way, humility is the best way to get out of the way of what God wants to do!
God can accomplish more in one day than you can accomplish in a thousand years, but you’ve got to posture yourself in humility. You’ve got to stay humble, stay hungry. Getting on your knees is the surest and fastest and truest way to get where God wants you to go.
Hit your knees!
— Mark Batterson

God descends to the humble as waters flow down from the hills into the valleys.
— Tikhon

Every one that exalteth himself shall be humbled; but he that humbleth himself shall be exalted.
– Amplified Bible (Luke 18:14)

There is no room for God in him who is full of himself.
— Martin Buber

When you are humble, you enjoy the blessings of My love, joy, peace, faith, patience, understanding, and the fruits of My Spirit in your life. These bless you in your interactions with others, and smooth over the rough edges. They make your relationship with Me more alive and real, because you realize how much it is My blessing in your life that gives you happiness, rather than anything you could work up yourself.
– Jesus, speaking in prophecy

God puts a great price on humility of heart. It is good to be clothed with humility as with a garment. It is written, “God resisteth the proud, but giveth grace to the humble.”(James 4:6) That which brings the praying soul near to God is humility of heart. That which gives wings to prayer is lowliness of mind. Pride, self-esteem, and self-praise effectually shut the door of prayer. He who would come to God must approach Him with self hid from his eyes. He must not be puffed up with self-conceit, nor be possessed with an overestimate of his virtues and good works.
Humility is not abstraction from self, nor does it ignore thought about self. Humility is born by looking at God and His holiness. A true nobleness and greatness are in humility. It knows and reveres the inestimable riches of the cross, and the humiliations of Jesus Christ.
– E. M. Bounds

The clearest way to identify humility is to see if the person is Christ-occupied or self-occupied. When somebody is arrogant, proud and self confident he is clearly self-occupied. At the other extreme, someone who is always fearful also has a problem with pride even if he appears to be very soft spoken and gentle. Instead of looking to Jesus, this person is self-conscious and constantly looking at himself. Both extremes are manifestations of pride. While one extreme manifest pride in terms of arrogance, the other extreme manifest pride in terms of self-consciousness. As long as a person is occupied with self, that is still pride. Humility then, is being Christ-occupied. This person knows that without the Lord, he cannot succeed, but with the Lord, all things are possible.
– Joseph Prince

The sacrifices of God are a broken spirit; a broken and contrite heart, O God, you will not despise.
– Psalm 51:17 NIV

Though the Lord be high, yet hath he respect unto the lowly: but the proud he knoweth afar off.
– Psalm 138:6 KJV

For this is what the high and lofty One says—he who lives for ever, whose name is holy: “I live in a high and holy place, but also with him who is contrite and lowly in spirit, to revive the spirit of the lowly and to revive the heart of the contrite.”
– Isaiah 57:15 NIV

By humility and the fear of the Lord are riches, and honor, and life.
– Proverbs 22:4 KJV
