1 Corinthians 1:18-25
18For the word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God. 19For it is written, "I will destroy the wisdom of the wise, and the cleverness of the clever I will thwart." 20Where is the wise man? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world? 21For since, in the wisdom of God, the world did not know God through wisdom, it pleased God through the folly of what we preach to save those who believe. 22For Jews demand signs and Greeks seek wisdom, 23but we preach Christ crucified, a stumbling block to Jews and folly to Gentiles, 24but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God. 25For the foolishness of God is wiser than men, and the weakness of God is stronger than men.
1I will bless the LORD at all times; his praise shall continually be in my mouth. 2My soul makes its boast in the LORD; let the afflicted hear and be glad. 3O magnify the LORD with me, and let us exalt his name together! 4I sought the LORD, and he answered me, and delivered me from all my fears. 5Look to him, and be radiant; so your faces shall never be ashamed. 6This poor man cried, and the LORD heard him, and saved him out of all his troubles. 7The angel of the LORD encamps around those who fear him, and delivers them. 8O taste and see that the LORD is good! Happy is the man who takes refuge in him!
13"You are the salt of the earth; but if salt has lost its taste, how shall its saltness be restored? It is no longer good for anything except to be thrown out and trodden under foot by men. 14"You are the light of the world. A city set on a hill cannot be hid. 15Nor do men light a lamp and put it under a bushel, but on a stand, and it gives light to all in the house. 16Let your light so shine before men, that they may see your good works and give glory to your Father who is in heaven. 17"Think not that I have come to abolish the law and the prophets; I have come not to abolish them but to fulfil them. 18For truly, I say to you, till heaven and earth pass away, not an iota, not a dot, will pass from the law until all is accomplished. 19Whoever then relaxes one of the least of these commandments and teaches men so, shall be called least in the kingdom of heaven; but he who does them and teaches them shall be called great in the kingdom of heaven.
