Prayer.
The focus of prayer is communion with God. It's intentionally, and unselfishly, leaning into his nearness through conversation, reflection, petition, and most importantly, just being with Him.
When we pray things happen. When we intercede, situations shift. When we are diligent, the tide begins to turn. We consecrate 21 days at the beginning of the year to prayer because it makes a huge difference in the purposes of heaven bearing fruit.
