In Mark 15:29-31 we read:
And those who passed by blasphemed Him, wagging their heads and saying, “Aha! You who destroy the temple and build it in three days, save Yourself, and come down from the cross!” Likewise, the chief priests also, mocking among themselves with the scribes, said, “He saved others; Himself He cannot save.
Save Y0urself. Really how strange was to these men that, He, that had saved many, was now on the cross, not caring for His own self. The one that serves himself, thinks it as very strange when he sees someone that denies doing the same. He that could have twelve legions of angels (1 legion = 6826 men), denied Himself, and became obedient to the point of death, even the death of the cross, calling us also to have the same mind with Him:
Let this mind be in you which was also in Christ Jesus, who, being in the form of God, did not consider it robbery to be equal with God, but made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross.
Then He said to them all, If anyone desires to come after Me, let him deny himself, and take up his cross daily, and follow Me. For whoever desires to save his life will lose it, but whoever loses his life for My sake will save it.
Jesus Christ denied Himself. He lost His life, yet not forever. After three days and three nights, God raised Him from the dead. As Philippians says:
Therefore God also has highly exalted Him and given Him the name which is above every name, that at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth, and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
The road that Jesus Christ pointed is a narrow road (Matthew 7:14). It is a road that someone walks not by keeping his life but by losing it. However, it is also the road of the resurrection. It may be that the crucifixion of the old man, the self, brings pain, but crucifixion is always followed by resurrection. We do not want to avoid the pain of the crucifixion, for without crucifixion there is no resurrection. We do not want to have the old man living in our hearts, but the new one, The Resurrected Christ. He is our Alive example and the one to whom we should look at:
Let us run with endurance the race that is set before us, looking unto Jesus, the author and finisher of our faith, who for the joy that was set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God.
From the very beginning of the Christian life, God expects obedience from those who put their trust in Him. Obedience to Him will save His people from the attacks of the evil one. It will save us from making the mistake of losing blessings by calling Him Lord, Lord, and not doing what He says. Jesus warned Not everyone who says to me, Lord, Lord, will enter the kingdom of heaven, but only he who does the will of My Father who is in heaven.
Obedience is not learned gradually. It is the step of faith necessary to assure victory. Obedience is expected at the very start of our Christian life. Age has nothing to do with a degree of obedience. Obedience is a decision of the will that every Christian can and should make by faith. Is this too costly? It is more costly if you fail to obey Him!
Conclusion: When you choose to obey the Lord, He will bless you. This is because obedience always leads to blessing. I have always told people who say they do not understand why God is asking them to do a certain thing that if they will obey Him, He will reward them with a sense of peace and joy that compares to nothing this world has to offer. Therefore, set a goal to obey the Lord and watch Him work in your life.
