For if by the one man’s offense death reigned through the one, much more those who receive abundance of grace and of the gift of righteousness will reign in life through the One, Jesus Christ.
Those who are in Christ Jesus are not to be ruled by what happens in life, but to rule in this life they live. We can reign in life through the abundance of grace He offers, and through His gift of righteousness. James 4:6-7 tells us that God gives grace to the humble, therefore submit to God, resist the devil and he will flee from you.
When we choose to submit ourselves to what God’s Word teaches us as New Testament believers, we are automatically resisting the devil, and in submitting to God we receive more grace (heavens help). In doing so we are reigning over the devils attempts to lead us astray. To reign in this life we must also recognize God’s gift of righteousness which gave us right standing with God. We receive this gift the moment we are born again. We are not going to get right with God, we already are.
This gift of righteousness is what gives us as children of God the right to our authority in Christ Jesus. By exercising our authority through faith in the name of Jesus, we can trample on the powers of darkness. As we remain humble, submitting to God and resisting the devil, and use the authority God has given to us through His gift of righteousness, using the name of Jesus, we can reign victorious in this life.
