Fish and trees grow throughout their lives. Trees top off in height at some point but continue to add rings around their trunks (some of us can relate to that analogy!). But nothing limits a fish from continuing to grow proportionately in size for as long as it swims! Of course, we humans do stop growing (apart from weight gain) and after we reach adulthood and as we move into senior citizen status we actually can shrink a bit! But this is just the physical dimension. We are also spiritual beings and the Lord has fashioned us to continue growing in that dimension for as long as we live (even if we can no longer swim!). The apostle Peter talked about the excitement of this spiritual growth in his letters:
2 Peter 1:3 By his divine power, God has given us everything we need for living a godly life. We have received all of this by coming to know him, the one who called us to himself by means of his marvelous glory and excellence.
2 Peter 1:2 May God give you more and more grace and peace as you grow in your knowledge of God and Jesus our Lord.
blessings to the spiritual fish!
