When we are saved unto eternal life by faith in Jesus Christ as our Lord and Savior we are sealed by God by the indwelling of the Holy Spirit who will then never leave us and who will be our guide, counselor and teacher in our walk with God. Let’s be clear who lives in us. In the following verse it is Jesus who is speaking:
John 14:23- If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him.
This verse tells us a lot. The Bible is God’s word and here Jesus says in My word so this is just another confirmation among many in the Bible that Jesus is God come to earth in the flesh. If you love Jesus you love God. If Jesus loves you so does the Father. If we love God we will obey the commands of Jesus. And because we love Him Jesus says We (Himself, the Father and the Holy Spirit) will come and make Our home with him. Again, Our means the trinity and live with him means on the inside of our body. You can refer to the indwelt Holy Spirit as any person in the trinity and be correct. By faith we are to accept the trinity as one God but three persons.
We can know and feel the presence of the Holy Spirit in our bodies with prayer and spiritual awareness. One one occasion I have felt the Holy Spirit in my body. Upon salvation my body has become God’s temple. Church attendance and fellowship is a good idea but my guide and teacher on all things is the Holy Spirit. Think of it as “home schooling” primarily done as the Bible is studied. For knowledge, understanding and wisdom it’s important for the believer to read the Bible daily, study God’s Word daily and pray often for God’s revelation.
