I believe we can “stand perfect and complete in all of God’s will” (Colossians 4:12). This unity with God’s will makes humans perfect [complete]. Full completion, accordingly, is a total adherence to God’s commandments.
Now, it seems that completion comes from one’s following God’s whole will fully. Such adherence, accordingly, seems to require a person to follow all of God’s commandments. If completion is following God fully and following God fully is following all of his commandments, a person who cannot do God’s commandments is not complete.
So are we to call everyone incomplete? Everyone’s incomplete because “no one calls on God’s name” (Isaiah 64:7). “No one on earth is righteous. No one does right and never sins” (Ecclesiastes 7:20). All people have sinned and transgressed against God (Romans 3:23; 1 John 1:10). What does Scripture call everyone, other than sinners who can’t follow God’s will fully?
Remember, the world defines perfection as the static and attainable condition of worldly success. This definition of perfection makes humans fully responsible for their perfection. Accordingly, such full responsibility requires people to have altruistic and kind characteristics.
The altruistic way to completion
The world thinks it can be perfect with conduct and that this “perfect” conduct leads to perfection. Such perfect conduct includes empathy, honesty, kindness, and fairness among others. Thus, the more a person’s characteristics appear empathetic, honest, kind, and fair, the more that individual is perfect. “If I can feel others’ pain, I will be perfect,” the world says. “When I expect nothing in return for my giving, I will be perfect,” the world says.
Oh, how the world thinks human conduct manufactures perfection. Nevertheless, perfection is God’s creation. God’s version of perfection—which is the true version—existed before people. Therefore, people’s habits and characteristics, regardless of their merit, are inconsequential to perfection.
Completion as God’s grace
It is higher to think “completion in God’s will” is to exist in his loving and gracious act towards humanity—the sacrifice of his son Jesus Christ. This existence (which is to exist before God and in God’s redemptive will) means to align ourselves with this action—the sacrifice of Jesus Christ for our sins. In other words, we shouldn’t attempt to align with human actions but God’s actions toward us. Perfection rests in a place of participation, leisure, and enjoyment. Although perfection is a gift, the world makes people work too hard for perfection.
So we read that “the God of hope can fill us with all joy and peace as we believe in him. Such fulfillment overflows with hope, through the power of the Holy Spirit” (Romans 15:14). God must fill people with good attributes because he is the only one who knows what “good” is. This process of completion (or perfection) that God initiates helps us to teach and interact with others (Romans 15:14). Benevolence to others is not absent totally with this process. However, God initiates and determines how we interact with others, not our feelings. Scripture says that God fills us with the “fruit of righteousness,” and this righteousness “comes through Jesus Christ” (Philippians 1:11). Jesus Christ is the only way people start the completion process.
Christians know that they are not responsible for their good attributes. “God must perfect me as I believe in Jesus Christ,” the Christian says. The Christian says, “I may act perfect and appear to have no flaws, but I’m nothing compared to the perfection of Jesus Christ. I will be complete according to the Lord.”
God must start the completion process
Some might wonder what is the completion of God’s will. A similar question is in Scripture. “They asked Jesus, What must we do to do the works God requires” (John 6:28)? “Jesus answered, The work of God is this: to believe in the one God sent” (John 6:29). The one thing we should do is not a disconnected act of kindness but have faith in Jesus Christ.
One should see perfection and completion as a process God initiates. When a person sees perfection in this manner, that individual won’t try so hard to be perfect alone. Since God is perfect and initiates perfection through our belief in Jesus Christ, the only thing we must do to be perfect is believe in Jesus Christ. All the “good” fruits (attributes) after belief in Jesus Christ will follow.
