"If anyone serves me let him follow me" -Jesus

Is this word from Jesus not part of our Gospel?   Is embracing this word from Jesus not part of our believing in Him?

And Jesus answered them, saying, "The hour has come for the Son of Man to be glorified. "Truly, truly, I say to you, unless a grain of wheat falls into the earth and dies, it remains alone; but if it dies, it bears much fruit. "He who loves his life loses it, and he who hates his life in this world will keep it to life eternal. "If anyone serves Me, he must follow Me; and where I am, there My servant will be also; if anyone serves Me, the Father will honor him.  (Joh 12:23-26)

Jesus was perfectly loyal to God and perfect in self-sacrificial love for fellow man.  Aren't you glad that God calls you to follow no one less?

By loyalty we are united to Jesus Christ, He is our Unity.

The basis for unity of all who are spiritually congregated around Jesus is Jesus himself. When Paul writes to Timothy (1Tim.3:15) and describes “the congregation of the living God” as the pillar and support of the truth, He is continuing to think of those truly united to God…the remnant of Israel, as opposed to the larger, but disloyal, body of people called Israel, who nonetheless still congregated periodically at the temple in Jerusalem. There is a unity  which I ought to charitably assume belongs to those individuals marked by loyal acknowledgment of Jesus (not circumcision). It is those who are marked by loyalty, or loyal acknowledgment, to Jesus who are spiritually congregated around Jesus. Their unity is expressed locally when disciples gather together on the basis of nothing more, and nothing less, than shared loyalty to Jesus. Loyalty to Jesus, with Him as our distinct, and singular point of unity, requires a supernatural focus and I think that is why Jesus was praying we would have this unity in John 17.

Exodus 32 and Acts 15...The Golden Calf and Idolatry

In Exodus 32 we see the people of God engaging in a favorite activity of man...honoring God through honoring an image. But the living God is against this activity.  Maybe it has something to do with the perversion of man shaping the living God rather than the living God shaping man.

In the New Testament Jesus gives the commands of the kingdom but they don't seem too workable as a baseline ethic...even for those embracing his authority. Rather, his ethic is one that must be pressed toward out of loyalty to him.  Worldly governments do pretty well at having baseline ethical standards. A baseline ethical standard is what God provided for national Israel within the Mosaic law.  But in Acts 15 it is very clear that Gentiles, who are joined to the Israel of God by faith, are not given the baseline ethic of the Mosaic law...perhaps that will be left to the nations in which they happen to sojourn.  So at this point (Acts 15) the apostles do send out a bare essentials, baseline ethic, for the adopted gentiles.
The gentiles will fare well if they keep to these "essentials" as a baseline ethic, no matter what earthly law they may be subject to in the empire and beyond. The four item list of essentials has a history of difficult translation and interpretation that would be interesting to discuss in another post but one element of these essentials is to abstain from the pollution of Idolatry.  Here are a few excerpts from a document linked to at the left on the topic of Idolatry.

“How could they do it?” and “I promise I would never treat God that way.”  These were my thoughts as a child; thoughts provoked by a story taught in Sunday school about the children of Israel and their golden calf.

“How could they do it?”

    We should maintain a sense of indignation for the Israelites readiness to rationalize the revealed will of God out or their minds.  As more mature Sunday school students, however, we must confess that we are very much like them.

“I promise I would never treat God that way.”

    In as much as this child-like response to the story of the people’s idolatry represents naive presumption, it should be corrected. Not being naïve children, we should not think of ourselves to highly as if we could swear an oath not to sin. In as much as this response represents a sincere desire to please God and obey His Word, we should cling to it.  Christian persons and churches should guard themselves from the sort of hardness of heart that many of the Israelites experienced and were slain.  For even when Moses came to them with the written Word of God and called out “who is on the Lord’s side,” not all of them were willing to repent.
