Anyone who lives on milk, being still an infant, is not acquainted with the teaching about righteousness. But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil. Hebrews 5:13-14
Our faith is a journey just like our lives are. The Bible describes when we first come to faith, or just start reading The Bible, we are like an infant on milk. What does this mean? Think about an infant, when they first start feeding its on only milk or formula. But as a child gets older and stronger, the child now requires solid food.
This is the same with us spiritually. When we first come to Jesus, many of the subjects in The Bible are foreign to us. We can digest the basics, but have a harder time digesting the tougher issues or lessons. But the more we mature in our faith, and as The Holy Spirit leads and guides us, we understand Gods plan and purpose for humanity.
I remember when I first starting studying The Bible, the story about Abraham going to sacrifice his son Isaac really offended me. I thought to myself this story can’t be true, how could God have told Abraham to do this? But as I got wiser I realized, this purpose of this story was to show us how much God loves us by sending his only Son to be sacrificed and save us for our sins.
Typically when anyone hears the story of Isaac they are offended or troubled, but when we hear about what Jesus has done, we just shrug and take it for granted. Put into context what Christ has done for us by going to the cross for you! God never intended to hurt Isaac, as the nation of Israel came through him. God wanted us to understand how much he gave and loved us, so we may live also
