The Lord draws our attention to the fact that, if we ever get to a point where we get to question His Love for us then we need to meditate on these Scriptures to find the clarity that we need in order to be grounded in the Truth of His promise for us. So the reference draws our attention to a mother's love that we are all familiar with to focusing on the Divine Love of God. This comes as a consolation that irrespective of what we have to face or deal with, the Love of God for us is an assurance and never changes.
Let us strive to fix our eyes on Jesus who is the leader and perfecter of our faith. (Heb 12:2)
