1 John 2:15 Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him. ~ In this passage of scripture, love means to be a friend of, to be fond of, have affection for, personal attachment, a deliberate assent of the will.
John is warning us to guard our hearts and to not embrace the belief systems of the world lest through the constant on-slot of attacks against standards of righteous, holiness, and purity, (through the media and other avenues) our foundations be eroded and we err from truth and holiness. We have to be cautious that we not allow the belief system of the world redefine our beliefs and our faith. The Bible says that in the end times gross darkness will cover the earth. We are starting to see that increased in a greater rate than ever before. We are seeing where much of the church is embracing a doctrine where scripture is not needed but only look to Jesus. We see where the acceptance of homosexuality and drug use is starting to become accepted and embraced by the world. These are sins and abominations unto God and we have to be careful that we not allow outside influences to redefine what is right and wrong. It is absolutely imperative that we are in the word and allow the Holy Ghost to teach us and define truth in our lives according to the Holy Scriptures. We must protect ourselves, our gates (hearing, seeing), and hold fast to the word of God if we want to hear well done good and faithful steward, enter into the joy of the Lord.
