That makes more sense than trying to turn it into a sin. Christians have this belief that the only way to get people to live right is to put them on a guilt trip. What better way than to say, "That's a sin."
Right. God wants obedience as an honest response to His love, not as a result of a guilted conscience. However, the Holy Spirit's conviction, especially through the Word of God, is much needed in a believer's life in order to follow the Lord and allow His santification to be worked out in you.
Philippians 2:12-13
"So then, my beloved, just as you have always obeyed, not as in my presence only, but now much more in my absence, work out your salvation with fear and trembling; for it is God who is at work in you, both to will and to work for His good pleasure."
I am not seeking to guilt anyone. I would be made to be a liar were I to say that I have not masturbated. I am "guilty" of it as much as the next man (or was, because marriage changes things a little, haha). However, I am out to seek the guidance of the Holy Spirit and the truth of God's Word, along with the sanctification of myself, the edification of Christ's Body, and the glorification of our Lord! My only desires are that we not be hinderances to each other in this matter, that we remain pure and upright before the Lord and before men (our testimony), that we edify each other, glorify our Savior and increase in the grace and knowledge of our Lord.
2 Peter 3:17-18
"You therefore, beloved, knowing this beforehand, be on your guard so that you are not carried away by the error of unprincipled men and fall from your own steadfastness, but grow in the grace and knowledge of our Lord and Savior Jesus Christ. To him be the glory, both now and to the day of eternity. Amen."
Remember how Paul starts 1 Corinthians 8 and Romans 14 (they "gray" areas passages)?
1 Corinthians 8:1
"Now concerning things sacrificed to idols, we know that we all have knowledge. Knowledge makes arrogant, but love edifies."
Romans 14:1
"Now accept the one who is weak in faith, but not for the purpose of passing judgment on his opinions."
Much love in Christ.
