The cross of Christ was in the center of the three crosses the day Jesus was crucified (John 19:17-19), but it’s not because Jesus was self-centered (Mark 15:27-28).
From his birth to his death, Jesus led a life of self-denial (Philippians 2:5-8). This self-denial wasn’t denial for the purpose of denial in-and-of-itself. Nor was Jesus’ self-denial for purpose of making himself the center of attention (John 14:10). Jesus’ self-denial was for the purpose of helping others and glorifying his father in Heaven (Acts 10:36-38; Matthew 5:16).
Self-centeredness must be cast aside to follow Jesus. Look at the context of Paul’s, “Let this mind be in you…” statement in Philippians 2:5. The context is getting rid of self-centeredness (Philippians 2:1-4). It’s then that Paul proves his point by using Jesus as an example as to why the church at Philippi (and us today) should look beyond their own circle of self when it comes to dealing with others.
But in case you have some unreasonable reason that causes “Paul’s words” to carry no weight with you – keep Luke 9:23 in mind and get over yourself.
“We then who are strong ought to bear with the scruples of the weak, and not to please ourselves. Let each of us please his neighbor for his good, leading to edification. For even Christ did not please Himself; but as it is written, “The reproaches of those who reproached You fell on Me.” For whatever things were written before were written for our learning, that we through the patience and comfort of the Scriptures might have hope. Now may the God of patience and comfort grant you to be like-minded toward one another, according to Christ Jesus, that you may with one mind and one mouth glorify the God and Father of our Lord Jesus Christ. Therefore receive one another, just as Christ also received us, to the glory of God.” (Romans 15:1-7 – NKJV)
