Paul tells us in Philippians 2 that we should have the same attitude as Jesus himself.

"5 In your relationships with one another, have the same mindset as Christ Jesus:

 6 Who, being in very nature[a] God,     did not consider equality with God something to be used to his own advantage;  7 rather, he made himself nothing     by taking the very nature[b] of a servant,     being made in human likeness.  8 And being found in appearance as a man,     he humbled himself     by becoming obedient to death—        even death on a cross!

 9 Therefore God exalted him to the highest place     and gave him the name that is above every name,  10 that at the name of Jesus every knee should bow,     in heaven and on earth and under the earth,  11 and every tongue acknowledge that Jesus Christ is Lord,     to the glory of God the Father."

Philippians 2:5-11 NIV

The magnitude and beauty of Christ's sacrifice amazes me!
