In today's second reading, Philippians 2: 1-11, St. Paul admonishes us to do "nothing out of selfishness or out of vainglory; rather humbly regard others as more important than yourselves, each looking out not for his [her] own interests, but also for those of others." Paul's statement--"but also for those [the interests] of others," implies that it is important to meet one's own needs and the needs of others. Self-neglect will lead to anger and resentment.
In terms of doing "nothing out of selfishness or out of vainglory; rather humbly regard others as more important than yourselves," we have Jesus as an example of these behaviors. "Christ Jesus,...though he was in the form of God, did not regard equality with God something to be grasped [vainglory]. Rather, he emptied himself [for our sakes] taking the form of a slave, coming in human likeness; and found human in appearance, he humbled himself, becoming obedient to the point of death, even death on a cross" [regarding us more important than himself].
In today's responsorial psalm, Psalm 25, we pray: "Your ways, O Lord, make known to me; teach me your paths, guide me in your truth and teach me, for you are God my savior." Jesus teaches us, by example, to follow God the Father's way, as He, in fact did throughout his life for our sakes. As a disciple of Christ, you and I are challenged to set aside our pride and selfishness and, with the courage, wisdom, humility, and generosity of Jesus to do as He did--give our lives for others! May God give us the graces today to follow Jesus' example.
