1.“Be true to yourself.” Jesus said, “… If anyone would come after me, let him deny himself and take up his stake and follow me. For whoever would save his life will lose it, but whoever loses his life for my sake will find it.” (Matthew 16:24-25) “Since therefore Christ suffered in the flesh, arm yourselves with the same way of thinking, for whoever has suffered in the flesh has ceased from sin, so as to live for the rest of the time in the flesh no longer for human passions but for the will of God.” (1 Peter 4:1-2 ESV)
2.“Follow your heart.” Jesus said, “And whoever does not take his stake and follow me is not worthy of me.” (Matthew 10:38) “He who trusts in his own heart is a fool, but whoever walks wisely will be delivered.” (Proverbs 28:26 NKJV) “The heart is deceitful above all things, And desperately sick; Who can understand it?” (Jeremiah 17:9 ESV)
3.“Believe in yourself.” Jesus said, “Believe in God; believe also in me.” (John 14:1 ESV) Jesus also said, “For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day.” (John 6:40 ESV) “Trust in the LORD with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths. Be not wise in your own eyes; fear the LORD, and turn away from evil.” (Proverbs 3:5-7 ESV)
4.“Live your truth.” Jesus said, “I am the way, and the truth, and the life. No one comes to the Father except through me.” (John 14:6 ESV) “This Jesus is the stone that was rejected by you, the builders, which has become the cornerstone. And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.” (Acts 4:11-12 ESV)
5.“As long as you are happy.” Jesus said, “For what will it profit a man if he gains the whole world and forfeits his soul? Or what shall a man give in return for his soul?” (Matthew 16:26 ESV) “Draw near to God, and he will draw near to you. Cleanse your hands, you sinners, and purify your hearts, you double-minded. Be wretched and mourn and weep. Let your laughter be turned to mourning and your joy to gloom. Humble yourselves before the Lord, and he will exalt you.” (James 4:8-10 ESV)
6.“You’re a good person.” Jesus said, “… No one is good except God alone.” (Mark 10:18 ESV) “… None is righteous, no, not one; no one understands; no one seeks for God. All have turned aside; together they have become worthless; no one does good, not even one.” (Romans 3:10-12 ESV) “Surely I was sinful at birth, sinful from the time my mother conceived me.” (Psalm 51:5 NIV) “Surely there is not a righteous man on earth who does good and never sins.” (Ecclesiastes 7:20 ESV)
7.“God helps those who help themselves.” Thus says the LORD: “Cursed is the man who trusts in man and makes flesh his strength, whose heart turns away from the LORD.” (Jeremiah 17:5 ESV) “For while we were still helpless, at the right time Christ died for the ungodly.” (Romans 5:6 NASB95)
To counter 1 & 2: There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus. And if you are Christ's, then you are Abraham's offspring, heirs according to promise. (Galatians 3:28-29 ESV)
To counter 3: And Jesus came and said to them, "All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age." (Matthew 28:18-20 ESV) But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth." (Acts 1:8 ESV) and said to them, "Thus it is written, that the Christ should suffer and on the third day rise from the dead, and that repentance for the forgiveness of sins should be proclaimed in his name to all nations, beginning from Jerusalem. (Luke 24:46-47 ESV)
Your counter to points 1 and 2 aren’t the words of Jesus but of Paul.
And what are we to make of the contradictory nature between our respective point 3s?
That Jesus contradicted himself.
Nietzsche had it right when he said that Christianity was a Jewish revenge.
