11 For the grace of God has appeared that offers salvation to all people. 12 It teaches us to say “No” to ungodliness and worldly passions, and to live self-controlled, upright and godly lives in this present age, 13 while we wait for the blessed hope—the appearing of the glory of our great God and Savior, Jesus Christ, 14 who gave himself for us to redeem us from all wickedness and to purify for himself a people that are his very own, eager to do what is good. — Titus 2:11-14 NIV
When we repented of our sins and received God’s forgiveness, it was the first step of a journey that will eventually take us to heaven to spend an eternity with our Lord and Savior, Jesus Christ. Our salvation is secure because we are clothed in the righteousness of Jesus Christ. The change in us, at this point, is internal. Unless that change in our hearts’ desires is manifested externally those around us may not know that we have accepted Jesus. True repentance changes our hearts and our minds. Jesus set the example of what our lifestyle should be. The Holy Spirit, which now dwells in us, inspired the writers of the New Testament to write verse after verse telling us how our lives should change. We now say “no” to those fleshly desires that were once our way of life. Now we say “yes” to the Holy Spirit. Every day is a battle between evil (our flesh) and good (the Spirit). We are in a war and there is no neutral ground. If we aren’t moving forward, then we are losing ground. So, every day, we must arm ourselves with the full armor of God and fight the good fight.
8 Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour. 9 Resist him, standing firm in the faith, because you know that the family of believers throughout the world is undergoing the same kind of sufferings.10 And the God of all grace, who called you to his eternal glory in Christ, after you have suffered a little while, will himself restore you and make you strong,firm and steadfast. 11 To him be the power for ever and ever. Amen — 1 Peter 5:8-11 NIV
