None of us are sinlessly perfect. Everyone of us is aware of a specific sin in our lives. Some of us wonder if we are even saved because of that specific sin that is in our lives. Some of us are at war with the sin, while others are complacently allowing for it. Which group are you in?
We are endangered when we count on our own efforts to fight the sin, and then failing time and time again, only to have doubt come in and rob us of our assurance, or we justify our sin away as if it is only a trifle, no big deal, everyone does it, and we allow for it instead of fighting against it. We count on grace to keep us safe. Both ways of thinking are wrong. We should be at war with our sins, knowing that Christ has won the war against sin once and for all. It is our lot to stand in front of the enemy before us and engage in the fight with all we have, resting in the knowledge that the outcome of the war has already been secured even if we fail in our battle time and time again, but with practice and provision from the Holy Spirit, and God’s word, we should be strengthened. God will sanctify us, and mature us out of that fight into another fight. We will keep fighting sin until we die, and are resurrected into a glorified body, that will only do that which is pleasing to God.
If you find yourself in the other group, using grace as a license for sin, sitting back in defeat, without a hope of ever growing, don’t give in. Now is the time to stand up and fight. Don’t prove you were never saved at all. Don’t harden your heart to the calling of the Holy Spirit to get in the fight. Don’t have a false assurance of your conversion. “Test yourselves to see if you are in the faith; examine yourselves! Or do you not recognize this about yourselves, that Jesus Christ is in you—unless indeed you [a]fail the test?” 2 Cor 13:5 You might experience a pleasant surprise. If you get back in the fight, repent and ask Christ to forgive you, He will. You can have assurance of your salvation. You can know you are saved. You can know through the fight, successes and failures, that drive you back to the cross again and again for grace. Don’t focus on you and your fight. Focus on Christ and His fight. Focus on His victory over sin, death and the grave. Focus on His victory imputed to you by faith and enjoy the peace between you and God in the midst of the violent war against sin in your life.
