Spirituality is very simple. Jesus said in John 8:31, "If ye continue in my word, then are ye my disciples indeed." The key word there is "continue." Purpose in your heart that you will be one who continues. Purpose in your heart that you will not be a casualty or a member of the Laodicean church (Revelation 3:14-20). Decide that you will not be someone who is distracted with personal sins or involved in satanic evil. Purpose to continue in Jesus Christ's Word.
Many men are good husbands, and they will continue to be good husbands because they have purposed it in their hearts. Many ladies are godly wives, and because they have purposed it in their hearts, they will continue to be godly wives. Others are good students and conscientious friends to God because they have purposed it in their hearts.
If we continue in the Word then we are disciples, "learners" of the doctrine of Christ; then we will know the truth and the truth will set us free. God says, "There is a way to be free from bondage. There is a way to be free from carelessness, worldliness, and the fashions of this world. There is a way to be free from lust and self-centeredness. Just continue in the purpose of My Word so that I can make you free."
