We Love God!

God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)

Sexual lust is definitely a sin and the catalyst for masturbating. But is the actual act itself, apart from lusting in the mind a sin? I believe the answer to that is yes. Masturbation is an aberrant form of sexual intercourse which is to be enjoyed by a married couple only. There is nothing in the Bible which gives approbation to celibate sex [by oneself].

Did not [Jesus] say, "You are of your father the devil, for his works you do?" Why, then, should you mock God by saying, "Our Father which art in heaven." For how can He be your Father? Have you two Fathers? And if He be a Father, where is His honor? Where is His love? You neither honor nor love Him, and yet you presumptuously and blasphemously approach Him, and say, "Our Father," when your heart is attached still to sin, and your life is opposed to His law, and you therefore prove yourself to be an heir of wrath, and not a child of grace!
C.H. Spurgeon
