If your believe that Jesus Christ saved you and He is the Lord of your life, then the Holy Spirit lives in you. He is with you all the time and knows you better than you know yourself. He is even with you while you sin, but gives you a way out of every temptation. This is essential because the devil is always looking for ways to trip us up. Always. Without the Holy Spirit, we are much more vulnerable, with the Spirit, we are armed and dangerous. The better our relationship with Him, the more in tune we are to God’s path and purpose for our lives.
