"Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own?"
1 Corinthians 3:16; 6:19 (NKJV)
One of the greatest differences between the Old Testament and the New Testament has to do with the Holy Spirit. In the Old Testament the Holy Spirit would come on people to empower them to do the work that God had called those people to do. The problem was that the Holy Spirit was not available to everyone. However, today as New Testament believers in Jesus Christ, as Christians, we have the Holy Spirit in us! This is such a wonderful truth but it seems that a lot of Christians don't even know about it
In his first letter to the Corinthians Paul asked them the same question twice, "Don't you know that the Holy Spirit is in you"? These people were Christians so they already had the Holy Spirit in them. Salvation is a work of the Holy Spirit on the spirit of man (Titus 3:4-6) where someone becomes a new creation in Christ (2 Corinthians 5:17). Paul said in Romans 8:9 if you don't have the Spirit of God then you are not even in relationship with God. Once we become a Christian we have the Greater One, the Holy Spirit in us (1 John 4:4) and His job is to help us, teach us, and guide us (John 14:26, Romans 8:14).
The problem many Christians have today is what Paul was talking to the Corinthians about; do we recognize that the Holy Spirit is in us? Do we have our attention on circumstances, our feelings, other people's opinions or do we focus on the Helper we have living inside of us? If we put our attention on the Holy Spirit in us, if we allow Him to direct us and help us, then He will lead us into triumph (2 Corinthians 2:14), He will give us the strength we need (Ephesians 3:16), and He will guide us into the truth (John 16:13). Thank God for the Holy Spirit, let's allow Him to help us do what God has called us to do!
