The use of incense is found in the Bible, and is symbolic of things we offer to God. There are passages in scripture that describe prayer as being incense before God. The fellowship of God's people (I am summarizing) has been called "a sweet smell" to God. 2 Corinthians 2:15 says that we are the fragance or aroma, an agreeable smell of sacrifice ("incense," if you will) of Christ to God!
There is nothing magical or extra-spiritual about using incense. If you chose to use it, then enjoy God in Christ Jesus as you do so!
