As we read through Ephesians, Colossians, and 1 and 2 Timothy, we see that these churches were spiritually healthy as Paul last ministered in this region. But by the time Revelation was written, approximately thirty years later, five of these same churches had suffered serious spiritual decline. Ephesus had left its first love, and most of the rest had been infiltrated by false doctrine and sin. Only two of the seven that Jesus addresses are not condemned by Him in some fashion, Smyrna and Philadelphia, yet today none of the seven currently exist. So, what are we to make of this?
Remember how your fathers, in times gone by, defended God’s truth, and blush, ye cowards, who are afraid to maintain it! Remember that our Bible is a blood-stained book; the blood of martyrs is on the Bible, the blood of translators and confessors. The pool of holy baptism, in which many of you have been baptized, is a blood-stained pool: full many have had to die for the vindication of that baptism which is “the answer of a good conscience toward God.” The doctrines which we preach to you are doctrines that have been baptized in blood, swords have been drawn to slay the confessors of them; and there is not a truth which has not been sealed by them at the stake, or the block, or far away on the lofty mountains, where they have been slain by hundreds. Charles Spurgeon
“By this we know love, that he laid down his life for us, and we ought to lay down our lives for the brothers. But if anyone has the world’s goods and sees his brother in need, yet closes his heart against him, how does God’s love abide in him? Little children, let us not love in word or talk but in deed and in truth.” 1 John 3:16-18
A sign of a healthy Church is their adherence to the Word of God. The Word of God is the foundation and starting point for every aspect of the Christian life. The apostles’ teaching has been preserved for us in the New Testament so that we have God’s instruction. One can hardly over-emphasize the importance of sound, biblical teaching. The teaching of the Apostles had already circulated to the seven Churches of Revelation including the Church at Ephesus. So that Church was well aware of the inspired Word of God.
