His branches shall spread, and his beauty shall be as the olive tree, and his smell as Lebanon. – Hosea 14:6

(The Christian) has been a lily straight up, with no branches at all; but now his roots have struck deep into the ground, like the cedars of Lebanon; and the next thing he does is to send forth branches. He says, “I am a Christian; I cannot keep it a secret, I must let somebody know I am a child of God.” …I have no patience with some of you who talk about being secret Christians. I should think the man a deserter if he were to say, “Well, I am a soldier, but I do not like anybody to know it.” I should think that he did not belong to one of our good regiments surely, or he would not be ashamed of his colors. But there are many now-a-days that you scarce know whether they are Christians. Shall I tell you why? The awful fact is, that they are not Christians. “No man lighteth a candle and putteth it under a bushel.” You know what the consequence would be if he did,-it would burn a hole through so sure as it was a candle; and no man can have grace in his heart, and keep it a secret. I am sure it must come out; it is one of the things that cannot be concealed. You shall not tell me you can walk into worldly company, and never let it be known that you are a Christian; that you can live for months in a house, and keep it dark that a Christian is living there. If that is the case, I tell you the angels do not know it; for it is not a fact. He that is a child of God will be discovered; his conduct will be different from the rest of men. “Thy speech betrayeth thee,” said the maid to Peter. And our speech will betray us, if we are disciples. I beseech you, let me stir you up, my young friends, to make a more open profession of your faith. The Savior has done much for you; do not be ashamed of Him, I implore you, but begin to make a profession of Christ Jesus, your Lord.~ C.H. Spurgeon
