1. This is seen in Paul's assurance that man's realization of his weakness -- subjective faith -- is a condition of God's impartation to him of His grace and strength: "When I am weak, then am I strong"; "my strength is made perfect in weakness"; "I rather glory in my infirmities, that the power of Christ may rest upon me," etc. Here the apostle gives the recognition of His weakness as the condition of His triumph, through divine strength, over self and suffering and sin.
Paul shares that we must FIRST and foremost become humble and be aware that of our own strength, we cannot do much of anything. When we first know this, we are usually just starting to turn toward Jesus. We have an "Aha!" and can finally see that we are not the final source of our strength after all. This is step 1. This is the first blessing. Recognition that Jesus Christ is my Savior and I am forgiven.
Step 2 is the natural progression of Step 1. Accepting COMPLETELY that Jesus is my Savior and actually allowing Him to do His work in us. Step 1 is where "growth" in Him occurs. Step 2 is somewhat of an instant process, a "Pentecostal" descending of God's Spirit after the initial decision is made for Jesus.
This is just the beginning of this wonderful, anointed teaching of old that I sincerely believe holds important keys for the Christian church today. This world has virtually taken over even infecting the church with its carnal ways and beliefs. God's truth is true! There is power in God's Word by the implementation of its principles. The Church can be a mighty tower of strength and a mighty testimony in this world...but only if we can go another step. Step 2. And "Be ye perfect even as the heavenly father is perfect."
