It is impossible to serve the Lord without being a dedicated disciple. According to many, however, serving God is a relatively simple thing. Wimpy Christianity has largely become accepted practice in America, in which mere human virtue is put forth to carry the day. “Salvation” now often comes by works or simply by being a member of the correct denomination or church. Yet true Biblical salvation will cost everything. Grace is free, but the new birth demands total surrender and obedience to God.
“Everyone who comes to Me and hears My words and acts on them, I will show you whom he is like: he is like a man building a house, who dug deep and laid a foundation on the rock; and when a flood occurred, the torrent burst against that house and could not shake it, because it had been well built. But the one who has heard and has not acted accordingly, is like a man who built a house on the ground without any foundation; and the torrent burst against it and immediately it collapsed, and the ruin of that house was great.” [Luke 6:47-49]
The majority of Christians build on the wrong foundation. Real disciples build on the right one.
So then you are no longer strangers and aliens, but you are fellow citizens with the saints, and are of God’s household, having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone, in whom the whole building, being fitted together, is growing into a holy temple in the Lord, in whom you also are being built together into a dwelling of God in the Spirit. [Ephesians 2:19-22]
The above passage, penned by the apostle Paul, presents an excellent illustration of the Body of Christ, or House of the Lord. Notice that there is only one foundation? One household? One building? One dwelling place of God? The prophets led the way. John the Immerser was the last of the OT prophets. He prepared the new way of the Lord. The Lord brought a new covenant. The apostles took the teachings of the prophets as part of the new foundation, they themselves were the other part, and the Lord Jesus was the Cornerstone that made the whole thing work.
The apostles’ teaching, as put forth in the Book of Acts, was acquired from the Lord during His ministry. There was only one community then. There were no denominations. Everyone in that early community was filled with the Spirit of God, as mentioned by Paul in his letter to the Ephesians. All one must do to understand the apostles’ foundation is study their history. They were not working against one another. Each one of them was preaching the same message.
It was not until later and throughout the Church Age that their foundational message was fractured, discarded, fought against, and emasculated—by “Christians.” Hence, we presently have Christianity in many different and often competing forms. Where then, is “The One Household of God?” Is every “Christian” on the planet a member of God’s household in some mysterious non-descript way?
And coming to Him as to a living stone which has been rejected by men, but is choice and precious in the sight of God, you also, as living stones, are being built up as a spiritual house for a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ. For this is contained in Scripture: “BEHOLD, I LAY IN ZION A CHOICE STONE, A PRECIOUS CORNER stone, AND HE WHO BELIEVES IN HIM WILL NOT BE DISAPPOINTED.” This precious value, then, is for you who believe; but for those who disbelieve, “THE STONE WHICH THE BUILDERS REJECTED, THIS BECAME THE VERY CORNER stone,” and, “A STONE OF STUMBLING AND A ROCK OF OFFENSE”; for they stumble because they are disobedient to the word, and to this doom they were also appointed. But you are A CHOSEN RACE, A royal PRIESTHOOD, A HOLY NATION, A PEOPLE FOR God’s OWN POSSESSION, so that you may proclaim the excellencies of Him who has called you out of darkness into His marvelous light; for you once were NOT A PEOPLE, but now you are THE PEOPLE OF GOD; you had NOT RECEIVED MERCY, but now you have RECEIVED MERCY. Beloved, I urge you as aliens and strangers to abstain from fleshly lusts which wage war against the soul. [1 Peter 2:4-11] 
The preceding passage in no way speaks of some form of wimpy Christianity or an easy way. Instead, it speaks of a single unified body made that way through the very strict discipleship of the Lord, that of the prophets and apostles, and that of every single chosen member.
We have drifted. We have gone soft. That’s in part why there are so many idiots with false gospels in the world. The Book of Acts brings us back on course. The foundation of the apostles and prophets distinguishes the real household of faith from all imposters. The symbology is clear—there is only one Precious Cornerstone. He exists as both the chief Rock of the foundation and the prototypical example and blueprint from which the house is being built. As the Alpha and Omega—the First and the Last—the Beginning and the End, He both anchors and caps off The One Household of God.
