This phrase is batted about by people who make a claim to Christianity, yet have no biblical concept of what they are actually saying or how to achieve that goal. For openers, being a true Christian requires a calling from God. One cannot just decide on the spur of the moment at some evangelical assembly, to become a Christian by “giving one’s heart to the Lord.”
By definition, a true Christian is one in whom God’s Holy Spirit dwells, and who follows its lead. There are steps and a process to follow. One is called; repents, that is, turns away from sin; believes in Jesus Christ’s Sacrifice and the gospel of the Kingdom of God; and is baptized. We read in Acts 2:38: “Then Peter said to them, ‘Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit.’”
Even the Holy Spirit just does not fall upon someone at repentance, but hands must be laid on the person after the baptism, and this must not be done by just anyone, but only by one of God’s true ministers.
Acts 8:18 tells us: “And when Simon saw that through the laying on of the apostles’ hands the Holy Spirit was given, he offered them money.” Notice, it was by the laying on of the apostles’ hands that the Holy Spirit was received.
Christ said it was possible to worship Him in vain, as Mark 7:6-7 points out: “He answered and said to them, ‘Well did Isaiah prophesy of you hypocrites, as it is written: “THIS PEOPLE HONORS ME WITH THEIR LIPS, BUT THEIR HEART IS FAR FROM ME. AND IN VAIN THEY WORSHIP ME, TEACHING AS DOCTRINES THE COMMANDMENTS OF MEN.”’”
Notice again, the ones who were worshipping God in vain knew who God was and what He requires of us; that is, they apparently kept the Sabbath and the Holy Days, but their worship became in vain because they added so many petty regulations which were unnecessary, and they abrogated other godly commandments, such as the injunction to honor our parents. They had added man-made provisions, putting obstacles in the righteous path, so it became burdensome, and they had “liberalized” certain godly commandments, declaring them to be superfluous.
Religions of this world are following the god of this world, Satan the devil (Ephesians 2:2; 2 Corinthians 4:4). We know that this situation will be corrected once Christ returns to this earth, removes Satan and reveals the truth to mankind on what is acceptable worship to God.
But what about all so-called Christian churches? If they don’t teach and observe God’s commandments and accept the biblical truth as to who and what God is, they are following Satan’s deceptions—even though in many cases, they are not even aware of it. For instance, the Bible does not support Sunday worship or the keeping of Christmas, Easter and the rest of pagan-based holidays, which only steer away from the true God and His plan for mankind.
We are either true and believing, or nominal and professing Christians. By our fruits we will be known. What kind of a Christian are you?
