Sacrifice

Christ, who was “in very nature God” (Phil. 2:6 niv), chose to leave the perfection of heaven and live among sinful people. Laying aside His divine authority, He was born a helpless baby, completely dependent upon others. His first 30 years were spent in obscurity, without recognition of His Messiahship. During His public ministry, He faithfully carried out God’s plan all the way to His death on the cross. Jesus’ days on earth are an example to us of the sacrificial life (Rom. 12:1-2).
