This week’s study focused on the final external element which is critical for the ongoing life of every tree - the Sun. The Sun powers photosynthesis, the process that all green plants use to create their own food from the water and soil their roots absorb. Without the Sun, these raw elements would remain useless to trees. Likewise, the Holy Spirit is the final critical element in the life of every believer. It is He who dwells in the heart of believers, and who serves as a seal and guarantee of our salvation.
