Though one may be overpowered, two can defend themselves.
A cord of three strands is not quickly broken.
We are designed for relationships. We are created to be connected. In the Bible, we see again and again how relationship is at the core of God's story for His creation. Many will consider "punching" in & out at a church service to be enough. However, God has called us to more than what "punching" in & out can provide. If we are to spur & encourage one another one, wouldn't we have to have more of a relationship than an hour or two could yield? We must develop relationships that will allow for us to speak into one another's lives. We must create an environment where we can help one another to grow. We must spend time together. Relationships need time. I'm not suggesting a "commune". I'm just saying that we need to be intentional in making time in our life to develop connections/relationships. So often we feel our lives are too busy for such things. Time can be as simple as eating a meal together, going shopping together, or lending a hand helping. Living life together allows for depth to happen. In that depth you can begin to encourage & spur each other on in a way that will grow you closer together & in your relationship with the Lord. The strength that relationships bring to your faith can not be expressed enough. Together we are better.
