Our Burden-Bearing God
What burdens are you carrying today? An ill child? Financial need? Deteriorating health? Diminishing capacity? Loneliness? Indecision? Losing someone you love? Failed mentors? Injustice? Growth of wickedness? Isaiah warns that trusting in anything other than God will only increase those burdens making them even more burdensome.
