God's representative offers shelter for those of us who are weary of battling with the complications of the material world. The Supreme Being is our ultimate shelter and God's representative provides that shelter on behalf of the Supreme Being.
Now what is this shelter? As Jesus clarifies here, the shelter comes in the form of his teachings. Jesus clearly says “take my yoke upon you and learn from me.” This clearly communicates that the "yoke" or shelter Jesus is offering lies within his teachings.
And what are his teachings?
"'Love the Lord your God with all your heart and with all your soul and with all your mind.' This is the first and greatest commandment." (Matt. 22:37-38)Jesus' teachings are to love and serve God. To do God’s will. To praise the Supreme Being and think about God. To give our lives to the Supreme Being. This 'first and greatest' teaching of Jesus provides the “yoke” that Jesus wants his students and disciples to come within.
It is because within love for the Supreme Being comes a relationship: A relationship with God. This relationship provides us with shelter. This relationship provides protection.
Notice also that Jesus describes himself as being gentle and humble in heart. While Jesus at times was critical of those who are offending the Supreme Being and His messengers, it is clear from this statement that Jesus sees himself as primarily a humble loving servant of God.
As a surrendered loving servant of God, Jesus carries with him the Supreme Being’s compassion and the Supreme Being’s love for each of us. Thus Jesus has become the Supreme Being’s vessel of love and mercy. For this reason, this "yoke" that Jesus is offering is also full of God's love, kindness and compassion.
Many organized, ecclesiastical institutions sects do not appreciate this loving personal relationship between Jesus and the Supreme Being, and thus they do not have this "yoke" or shelter given by Jesus. Why not? Because they have not learned from Jesus' teachings.
Instead of seeing Jesus' life as one of loving service to God, they have translated Jesus' life and sacrifices in a self-centered manner. They believe that Jesus' sacrifice was all about themselves. It was all about saving me.
But that consciousness is the polar opposite consciousness that lies within Jesus' teachings - and the shelter being offered by Jesus within those teachings: Selfless love for the Supreme Being. Caring about the Supreme Being more than we care for ourselves. This why the greatest teaching says, all your heart.
