18 Children, it is the last hour, and as you have heard that antichrist is coming, so now many antichrists have come. Therefore we know that it is the last hour.19 They went out from us, but they were not of us; for if they had been of us, they would have continued with us. But they went out, that it might become plain that they all are not of us. 1 John 2:18-19
In God’s word the Lord continually warns us against false teaching, false teachers, lies and deceptions. The apostle John writes of this being the last hour. The last hour includes all the time of the church age. There is coming a day in which the Lord shall return for His bride. At that time He will remove her from the earth. After the bride has been removed the judgement of the Lord shall be poured out that is written of in the book of Revelation.
John speaks of the antichrist who is coming and many antichrist who have come. The antichrist will be a great receiver who will proclaim himself to be the savior of the world, but in the end will deceive those who give him their allegiance and will lead them into destruction. The same stands for the antichrist John speaks of having come. False teachers would continually try to come in and deceive the sons and daughters of God and it was the role of the apostles to bring correction and to guard the purity of God’s truth. They were commissioned by the Holy Spirit to write the Holy Scriptures through the inspiration and leading of the Holy Spirit.
The greatest way that we can guard our hearts against false teaching is to know the word of God. When we have a deep understanding of the truth of God’s word we will recognize that which is false and not true. Those who are deceived are those who ignore diligently studying the scriptures. The greatest investment we can make on this earth is in the diligent study of God’s word and in the place of prayer. That which is sown into the spirit will never be done in vain, but in due time we shall reap a great harvest.
