If Satan continues to hound you, call in help and do not listen to the devil’s counsel to the contrary. The very strength of some temptations lies in trying to keep them hidden. Telling a trusted, godly friend of your struggles often brings relief. Satan knows this too well, so in order more freely to rifle the soul of its peace and comfort he frightens it into silence.”Oh my”, Satan says, “if your friends knew such a thing of you, they would cast you off. You had better hope they never find out!” He has kept many a poor soul in misery by swearing it to secrecy. You lose two blessing by keeping the devil’s secret – the counsel of your fellow brethren and their prayers. What a serious loss this is!
