The second piece of the divine armor of protection for God’s warrior as described in Ephesians 6:13-18 is righteousness. Thus we’re commanded to “Put on the breastplate of righteousness,”
When we surrender our life to the Lord Jesus Christ that is when God justified us by placing the righteousness of Jesus Christ to our account. He “who knew no sin became sin for us so that we might become the righteousness of God in Him” (2 Cor. 5:21)
This righteousness of Christ is not only over us it is in us, because Jesus who is our righteousness lives within each person who has surrendered their life to Him. Wearing the righteousness of Christ produces living by God's holy commandments and God’s righteousness protects our life.
In order to develop righteousness or personal holiness we must win the every day fight to consciously and consistently follow God’s will and way. Satan looks for weakness or doubt in the believer’s spiritual armor so that he might turn our lives upside down. Without this personal sanctification vital areas in the believer’s life will be vulnerable (Ephesians chapter 4:24) reads "And that you put on the new man which is after God created in righteousness and true holiness".
If you possess emotional problems, have your priorities out of order or have a negative attitude, it will be difficult to put on the breastplate of righteousness. If your life does not line up with God's order, then you are open to attacks from the enemy who is looking for someone to devour, exploit, and destroy.
To keep the breastplate of righteousness intact we must obey God's purpose for our lives by keeping continuous communication with God to direct us. God gives us freedom to make our own choices, so we must choose to listen to His guidance and be obedient in following the foundations He has laid.
When we act in accordance to God's will this piece of our armor remains intact and protects us. The breastplate of righteousness is only one of the pieces of protection that God provides. Read Ephesians 6:13-18 to discover the other elements of God's protective armor.
