Luke Gilkerson of Breaking Free, the blog of Covenant Eyes, authored this post as an open letter to Christian men regarding pornography.
Luke describes the painful internal struggle that all pornography addicts endure — partly of their own choosing, partly not. One aspect Luke discusses is the importance of how life with porn is in direct opposition to life with God.
In fact, this is something we read about in 1 Thessalonians 4:3-8.
3 It is God’s will that you should be sanctified: that you should avoid sexual immorality; 4 that each of you should learn to control his own body[a] in a way that is holy and honorable, 5 not in passionate lust like the heathen, who do not know God; 6 and that in this matter no one should wrong his brother or take advantage of him. The Lord will punish men for all such sins, as we have already told you and warned you. 7 For God did not call us to be impure, but to live a holy life. 8 Therefore, he who rejects this instruction does not reject man but God, who gives you his Holy Spirit.
When we decide that we will satisfy our sexual impulses in a way that is apart from God, we are rejecting Him. Therefore, we can say that life with porn is life without God; it is a life in which we experience very little of His presence and the movement of His Holy Spirit. We put ourselves in the place of being like those who live only under His Common Grace, as opposed to living as true sons of God.
