The laws of nature are nothing more than acts of God which are being accomplished in a quiet way. There can be no laws without a lawgiver. The so called laws of nature are secondary causes, while God is the primary agent. He causes the sun to shine, the rain to fall, the grass to grow, and both fruit and grain to ripen. He does this to provide food for man and animal.
Man can plant, cultivate and water.
But God alone gives the increase. Ultimately I look at God as the Master Chef and Gardener. For it is really Him who has given us our daily bread. Man has to cooperate with the Lord's method by planting the seed, watering and cultivating the plant. Psalms fourteen and fifty three set forth that only a fool questions the existence of a Supreme Being.
