God cares more about our sanctification than our comfort.
God does allow suffering into our lives. Suffering shows us plainly our need for Him (if everything was sunshine and rainbows always then why would we ever even look for a savior?), it shows us who He is through the comfort and strength He lends us, it grows us into better versions of ourselves- pushing us beyond where we are comfortable- and into new lives, new directions. As the Father of compassion, He would not have us walk these new roads alone. There are others who have walked down those same paths, gained wisdom, learned how to endure, drew comfort from God Himself, and he will send them to come alongside you, sharing the comfort they received, lending you strength and hope because you know you will endure. Even suffering has its purpose, but we will not be made to go through it alone.
