Obedience is saying ‘yes’ when God tells you something to do (in an immediate sense). “If you love me you’ll keep my commandments;7” and “This is my commandment, that you love one another.” John 15:12. I cannot do right by myself. I can only do right as I surrender and trust God to work His will in me. Only as I die to myself, and let Jesus live His life in me,” (Galatians 2:20) can I live up to His standard, which is, “Be perfect (whole, complete, entire, wanting nothing), even as your Father in heaven is perfect.” Matthew 5:48
Philippians 2: 5-8 says, in a general way, “Let this mind [attitude] be in you which was also in Christ Jesus, . . . Who, being found as a man, . . . humbled Himself, and became a slave, and was obedient unto death, even death on a cross.” The point is that Jesus was obedient unto death; and we’re supposed to let that level of obedience be in us, to be like Jesus. We should do what it says in Luke 9:23 about deny yourself (your sinful nature), and take up your cross (the cross of death to you and Life from Him) daily, and follow Him.
