Colossians 2:6-8
6 So then, just as you received Christ Jesus as Lord, continue to live your lives in him, 7 rooted and built up in him, strengthened in the faith as you were taught, and overflowing with thankfulness.
8 See to it that no one takes you captive through hollow and deceptive philosophy, which depends on human tradition and the elemental spiritual forces of this world rather than on Christ.
Matthew 4:1-11
Then Jesus was led by the Spirit into the wilderness to be tempted by the devil. 2 After fasting forty days and forty nights, he was hungry. 3 The tempter came to him and said, “If you are the Son of God, tell these stones to become bread.”
4 Jesus answered, “It is written: ‘Man shall not live on bread alone, but on every word that comes from the mouth of God.’”
5 Then the devil took him to the holy city and had him stand on the highest point of the temple. 6 “If you are the Son of God,” he said, “throw yourself down. For it is written:
“‘He will command his angels concerning you,
and they will lift you up in their hands,
so that you will not strike your foot against a stone.’”
7 Jesus answered him, “It is also written: ‘Do not put the Lord your God to the test.’”
8 Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their splendor. 9 “All this I will give you,” he said, “if you will bow down and worship me.”
10 Jesus said to him, “Away from me, Satan! For it is written: ‘Worship the Lord your God, and serve him only.’”
11 Then the devil left him, and angels came and attended him.
Matthew 6:1
“Be careful not to practice your righteousness in front of others to be seen by them. If you do, you will have no reward from your Father in heaven.
Matthew 6:16-18
16 “When you fast, do not look somber as the hypocrites do, for they disfigure their faces to show others they are fasting. Truly I tell you, they have received their reward in full. 17 But when you fast, put oil on your head and wash your face, 18 so that it will not be obvious to others that you are fasting, but only to your Father, who is unseen; and your Father, who sees what is done in secret, will reward you.
