We all are familiar with the greatest commandment, that we are to love the Lord thy God with all thy heart, soul, mind and strength and love thy neighbor as thyself. When we do this, all the other commandments fall into place. Is this possible? I have no doubt it is possible through indwelling of Christ in us, the Holy Spirit. Is it probable? Not when the majority of the church has accepted doctrine(s) that claim it is either impossible or unnecessary.
Think about this... Jesus himself proclaim that there is no greater love than to lay one's life down for a friend. He then gave his life on the cross of Calvary that we might be saved. In turn, the early church of the 1st, 2nd & 3rd centuries understood this truth and gave their lives also so that the gospel could spread throughout the Roman Empire and into the far reaches of Europe, Africa and Asia. If you read the testimonies of these great men and women of God, you will notice that they had died to their own sense of self and the lusts of the world long before they gave their lives for the sake of the gospel.
What loving parent would not give or risk their life to save the life to save the life of their child? What loving parent isn't willing to sacrifice his or her own personal needs or desires for the sake of their children? Keeping this in mind, I believe it is very conceivable that a person can keep the greatest commandment but that many martyrs in the past have kept the first commandment through the leadership and empowerment of the indwelling Christ (Holy Spirit).
I personally believe that the reason why modern Christianity over the last couple of centuries looks and acts more like the world than it does Jesus or even the early church which existed during the centuries following Christ's life and death is because we have embraced doctrines of compromise which state that dying to one's own sin and selfishness is no longer required. Now whether or not dying to one's own self is a necessity for salvation, I'll leave that up to you to investigate. However, I know for a fact that we will never have victory over the sin and selfishness that keeps us in mental, emotional or spiritual bondage until we are willing to let go and allow God to remove or world desires and selfish behaviors.
I also believe that because the majority of "believers" do not walk in victory over sin and self to be the reason why the gospel is seldom effective in areas like the United States and Europe where the majority of people view Christianity to be no different than Judaism, Islam, Hinduism or any other of the world's more prominant religions. People consider Christianity no different from any other religion because few Christians actually walk in true, genuine anointing of the Holy Spirit. But why? Could it be that it is our unwillingness to surrender to the work of the Holy Spirit through sanctification and give up our selfish desires and worldly lusts actually grieves the Holy Spirit as scripture implies?
In ending, I know that there are many on these boards who will disagree with me and do their best to discredit everything I have to say. However, if we are truly honest with ourselves and with God concerning scriptural Christianity in comparison to modern Christianity, I believe many will agree with my observations.
