As believers, we have been positioned to drink. This is the first aspect of the science of drinking….Through baptism we have been positioned to drink [1 Corinthians 12:13]. As long as we have been baptized into the Lord, we have the position to drink of the living water. Before we were saved, we were far away from the living water. But now that we have been saved, we have been brought back to the water and positioned to drink of it. For example, there is a drinking fountain in our meeting hall. But in order to drink of this fountain, our mouth must be in the proper position. Likewise, to drink of the living water, we must first be positioned to drink. Baptism gives us this position.
Even though we have been positioned to drink, we shall not drink unless we are thirsty. To drink the water of life there is the need of thirst (Exodus 17:3a; John 7:37; Revelation 21:6)….It is a mercy that we are thirsty for the living water, especially when so many Christians have no thirst. Many of us can testify that during the day we are conscious of the thirst within us. This thirst causes us to pray and to contact the Lord. In a simple way, we may say, “Lord Jesus, I am thirsty for You, and I want to contact You.” If we sense that our thirst is not adequate, we may need to pray, “Lord, increase the thirst within me.” We all need such a thirst for the Lord.
