Why?:
If you return to the Almighty [and submit and humble yourself before Him], you will be built up; if you put away unrighteousness far from you tents, (Job 22:23). For He who avenges the blood [of His people shed unjustly] remembers them; He does not forget the cry of the afflicted (the poor and the humble). (Psalm 9:12).

Think about it:
He leads the humble in what is right, and the humble He teaches His way (Psalm 25:9). For You deliver an afflicted and humble people but will bring down those with haughty looks (Psalm 18:27). For the Lord takes pleasure in His people; He will beautify the humble with salvation and adorn the wretched with victory (Psalm 149:4).

How?:
Let this same attitude and purpose and [humble] mind be in you which was in Christ Jesus: [Let Him be your example in humility:](Philippians 2:5). Humble yourselves [feeling very indinificant] in the presence of the Lord, and He will exalt you [He will life you up and make your lives significant] (James 4:10). Therefore humble yourselves [demote, lower yourselves in your own estimation] under the mighty hand of God, that in due time He may exalt you (1 Peter 5:6).

Think about it:
When they make [you] low, you will say, [There is] a lifting up; and the humble person He lifts up and saves (Job 22:29). Better it is to be of a humble spirit with the meek and poor than to divide the spoil with the proud (Proverbs 16:19).
