And he said, Nay; but I will die here…And the king said unto him, Do as he hath said, and fall upon him… – 1 Kings 2:30,31

Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved. – Acts 4:12

You may be a member of a church fifty years, but you will be damned at last unless you are a member of Christ. It matters not though you are a church-officer, a deacon, an elder, a pastor, a bishop, or even Archbishop of Canterbury, or an apostle, you will perish as surely as Judas, who betrayed his Master with a kiss, unless your heart is right with God. I pray you, put no confidence in your profession. Unless you have Christ in your heart, a profession is but a painted pageantry for a soul to go to hell in. As a corpse is drawn to the grave by horses adorned with nodding plumes, so may you find in an outward profession a pompous way of being lost. God save us from that!.. “My confidence is in my sound doctrine.” That is not mine, friend, and I hope that it will not be yours long, for many lost souls have firmly believed orthodox doctrine…Put no confidence in the mere fact that you hold to an orthodox faith, for a dead orthodoxy soon corrupts. You must have faith in Christ, or else this altar-horn of a correct creed, on which you lay your hand, will bring you no salvation.

Whatever you depend upon apart from the blood and righteousness of Christ, away with it! Away with it! If you are even depending upon your own repentance, and your faith, away with them! If you are looking to your own prayers or alms, I can only cry again, -Away with them! Nothing but the blood of Jesus; nothing but the atoning sacrifice; but, if you come and lay your hand upon that, blessed shall you be. Before the living God, who is greater and wiser than Solomon, it will be of no avail to any man to lay hold upon the horns of the altar. But, there is an altar-a spiritual altar-whereof if a man do but lay hold upon the horns, and say, “Nay; but I will die here,” he shall never die; but he shall be safe against the sword of justice for ever; for the Lord has appointed an altar in the person of His own dear Son, Jesus Christ, where there shall be shelter for the very vilest of sinners if they do but come and lay hold thereon. ~ C.H. Spurgeon
