John 1:29 (NKJV)
Revelation 5:5 (NKJV)
There is a saying that people have for the weather in the month of March that goes like this, "In like a lion and out like a lamb". What people mean is that the weather in the beginning of March is usually worse than the weather at the end of the month. This is because typically winter weather is still seen in the early part of the March while at the end of March the weather is milder and more like what is seen in the spring. This difference in how the weather changes from the start to the end of March is seen in other things where the way something starts is different from how it finishes.
In John 1:29 John the Baptist referred to Jesus as the Lamb of God who takes away the sin of the world. In 1 Peter 1:18, 19 it tells us that Jesus redeemed us by His blood. In the Old Testament sin was only covered by the blood of the sacrificial lamb but through the blood of Jesus, the Lamb of God, our sins have been washed away! However, what Jesus did for us did not end at the removing of our sins; Jesus overcame sin, sickness, depression, lack, and anything else that would hinder us from living the abundant life He came to provide for us (John 10:10).
Jesus paid the price for our sins as the Lamb of God and as the conquering Lion of the tribe of Judah, as He called in Revelation 5:5, He also gave us the ability to live a life free from the domination and oppression of the devil and sin. Jesus is the victor over sin, is seated at the Father's right hand, and has all authority in heaven and on earth. While Jesus did come into the world as a lamb, He finished His work and went out like a lion. We need to read and study the Word of God to get a full understanding of everything Jesus did for us and then walk in the benefits He provided for us.
