From the passage in Genesis, we know that God blessed humanity with purpose and in the fulfillment of purpose, there would be an increase or provision. When God said, “Be fruitful and multiply” (Genesis 1:28, ASV), He imparted a two-part blessing and mandate over humanity.
First, the call to fruitfulness is a call to productivity. Faithful work positions us for God’s provision. When we put our heart into our task, there will be significant benefits. It is the law of sowing and reaping (Galatians 6:7-9, ASV).
Second, it is a call to greatness. The mandate to multiply is not only numerical, it is noble. God is inviting us to greatness in becoming all that He envisions us to be. It is a promise of provision and of purpose. In other words, we will have what we need, and we will be able to meet the needs of others through our being all that God created us to be.
