"Infants tossed back and forth by the waves." - Ephesians 4:14

This warning speaks to the condition of the church when the work of evangelists, pastors and teachers is not successful. The ultimate goal of believers in the church is described by these three characteristics:

1) Unified in doctrine and knowledge (knowing the Truth)
2) Becoming mature (mature condition)
3) Attaining the whole measure of the fullness of Christ (production of fruit)

But, in order to reach this goal, the church will have to continue to ward off a three-pronged attack designed to keep believers ignorant of the doctrine and knowledge of God's Word.

The first attack is described as "the waves" that toss immature Christians back and forth. The waves are the instability caused by ignorance in believers who do not know the Word of God, and so they cannot adequately analyze or judge the teaching they hear. Without the anchor of Truth to secure their souls, the church is tossed about on the waves.

"blown here and there by every wind of teaching" - Ephesians 4:14

This refers to the second part of the three-pronged attack on the church's unified faith and knowledge. As the Christian struggles toward a destination of maturity, there are ever-changing winds of opinion and doctrinal teaching that move the waves in different directions, impeding the Christian's progress toward the truth.

"Cunning and craftiness of men in their deceitful scheming" - Ephesians 4:14

This danger refers to the third of the three attacks that have besieged the church throughout history. Not only are Christians metaphorically riding on rolling waves, trying to progress toward the goal of maturity, with a variety of winds of teaching causing chaos, but men (and Satan) are intentionally
scheming to twist and warp the teaching of the church to reflect their own position and lead Christians to it – which is not unity in doctrine, nor is it maturity.

a church that does not teach the Wiord of God will be left
to feed on a worthless form
of spiritual nutrition."

Jesus grew up in the house of a carpenter and was called a carpenter himself. The Greek word for "carpenter" is tekton which refers to a person who built things, but not necessarily only with wood. Tekton could refer to a stonemason also. The city of Sepphoris was being rebuilt only 4 miles north of Nazareth during Jesus childhood and youth. It is likely Jesus did construction work, including stone work, in Sepphoris with his father and as a independent contractor.
