"Come to me, all you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. For my yoke is easy and my burden is light."
-Matthew 11:28-30

Whatever you do, work at it with all your heart, as working for the Lord, not for men...
-Colossians 3:23

If you have any encouragement from being united with Christ, if any comfort from His love, if any fellowship with the Spirit, if any tenderness and compassion, then make my joy complete by being like-minded, having the same love, being one in spirit and purpose. Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves.
-Philippians 2:1-3

He has showed you, O man, what is good.
And what does the Lord require of you?
To act justly and to love mercy
and to walk humble with your God.
-Micah 6:8
