Belief >> Salvation: God decided even though we don't deserve it, to save us because we believe. (We are saved by grace through faith. Eph 2:8)
- How can I let the word dwell in me? By reading it. By obeying it, and obeying it is doing what it says. (Let the Word of Christ dwell in you richly. Col 3:16a; Do not merely listen to the word, and so deceive yourselves. Do what it says. Jas 1:22 If you Love me, you will obey me. Jn 14:15)
Obedience >> Purification: We are able to be purified when we obey the truth/word. Now that you have purified yourselves by obeying the truth so that you have sincere...
When we obey the truth we will love one another. ... Love for your brothers, love one another deeply, from the heart... We get rid of all the things that can hinder our purification. Therefore, rid yourselves of all malice and all deceit, hypocrisy, envy, and slander of every kind. And we are to grow up in our salvation. Like newborn babies, crave pure spiritual milk so that by it you may grow up in your salvation. 1Peter 1:22-23; 2:1-2
The world will be able to see we belong to Christ by our love for our brothers and sisters in Christ. By this all men will know that you are my disciples, if you love one another. Jn 13:35
Christ is like the mortar that holds all the living stones together in a bond of unity. In him, the whole building is joined together and rises to become a holy temple in the Lord. And in him you too are being built together to become a dwelling in which God lives by his Spirit. Eph 2:21-22
Remember that the weapons are spiritual. We are able to conquer our thoughts that pretend to be bigger than God by making our thoughts line up with the what Christ says. We need to make our thoughts obey Christ. For though we live in the world, we do not wage war as the world does. The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. We demolish arguments and every pretension that sets itself up against the knowledge of God, and take captive every thought to make it obedient to Christ. 2 Cor 10:3-5
Scripture tells us to put on love, put on Christ and put on armor of God etc. If we just deal with getting rid of our sinful behavior, yet do not take the time to put on all we are commanded, we will stand naked before our enemy and be very vulnerable. Therefore put on the full armor of God... with the belt of truth buckled around your waist, with the breastplate of righteousness in place, and with your feet fitted with the readiness that comes from the gospel of peace. In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. Take the helmet of salvation and the sword of the Spirit, which is the word of God. Eph 6:13-17
As our feet are fitted and ready, we go to the world with our good news not just on our lips, but also demonstrated in our actions. Therefore go and make disciples of all nations, baptizing them in the name of the Father and the Son and the Holy Spirit. Teaching them to obey everything I have commanded you... Matt 28:19-20
