The call to follow Jesus goes against what is natural to us
Phil 2:1-4
So if there is any encouragement in Christ, any comfort from love, any participation in the Spirit, any affection and sympathy, 2 complete my joy by being of the same mind, having the same love, being in full accord and of one mind. 3 Do nothing from selfish ambition or conceit, but in humility count others more significant than yourselves. 4 Let each of you look not only to his own interests, but also to the interests of others.
We need something outside of us to help change our mind
Phil 2:5-11
5 Have this mind among yourselves, which is yours in Christ Jesus,[a] 6 who, though he was in the form of God, did not count equality with God a thing to be grasped,[b] 7 but emptied himself, by taking the form of a servant,[c] being born in the likeness of men. 8 And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross. 9 Therefore God has highly exalted him and bestowed on him the name that is above every name, 10 so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, 11 and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.
Those with the mindset of Jesus have a way about them
Phil 2:19-21
19 I hope in the Lord Jesus to send Timothy to you soon, so that I too may be cheered by news of you. 20 For I have no one like him, who will be genuinely concerned for your welfare. 21 For they all seek their own interests, not those of Jesus Christ.
