Jesus, when talking to the woman at the well, referred to ‘living water' that would permanently quench thirst, a perpetual spring within those who received Him, culminating in eternal life (Jn 4:10-14). “With joy you will draw water from the wells of salvation…Let him who is thirsty come, and drink of the water of life”, then rivers of living water will flow from the innermost being of Christ’s believers (Isa 12:3; Jn 7:38,39; Rev 22:17).
These verses speak figuratively of the Holy Spirit’s dynamic life, always available and flowing to provide refreshment. It is our responsibility to be clean channels through which the Spirit can flow to bless others with the love and gospel of Christ. Sin, in a multitude of ways, prevents us receiving and then imparting the divine life-giving influence of the Holy Spirit to those in need. Because of the connection to the source of real life being blocked and there being no fresh outflow, any ministry to others will only be a product of the natural soul of man and largely ineffective as it lacks divine power.
A river of living water flowing from the throne of God in the new Jerusalem (new heaven) depicts the abundance and continuance of life in eternity (Rev 22:1,2).
