My father is an environmental engineer. He carefully designed a house for us that has a green house facing directly south to make the most use of the pale winter sunlight. In fact, it often works too well. When it is -40 outside, it can be 95 in the greenhouse. The advantage is that we can open the doors between the house and the greenhouse and heat our house with this captured sunlight.
Sometimes it just feels good to sit in the sun in the green house. It warms up chilly bones like a warm hug from God.
Likewise, when we walk in God's light, his love can warm our hearts and defrost our frozen feelings.
May we take opportunities to face the Son, and bask in his light, so we can warm our homes and all who enter there.
