We are completely justified through the sacrifice of Jesus on the cross. That is the great basis for mental peace. Once we know this, we have God on our side, and that makes all the difference in life.
Paul goes on in Romans 8:31-32, speaking on behalf of those of us who have received this reconciliation – who believe, according to Scripture, that they are justified. Paul says:
"What then shall we say to these things? If God is for us, who is against us? [That's a good question. Who can be against us if God is for us? Somebody expressed it this way: one plus God is a majority in any situation. Paul goes on:] He who did not spare His own Son, but delivered Him up for us all, how will He not also with Him freely give us all things?" (NASB)
Because God was willing to give Jesus, His most precious treasure, His only begotten Son, then we know that such love as that will hold nothing back that is good for us or that we need. If God gave up Jesus, there's nothing good He will ever withhold from us. God is on our side. He is for us. The resources of heaven are at our disposal. That is the basis of mental peace. Once we really comprehend by faith that we have been reconciled with God, that we are justified, that we are reckoned righteous with the righteousness of Jesus, that we can say, "I am justified, just-as-if-I'd never sinned," then we can move on into the complete and full provision of God for our mental peace.
This provision is stated clearly by Paul in Philippians 4:6-7, where he says this:
"Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all comprehension, shall guard your hearts and your minds in Christ Jesus." (NASB)
Notice that significant and beautiful phrase, "the peace of God, which surpasses all comprehension, shall guard your hearts and your minds in Christ Jesus". That is in line with what I said about the danger of a vacuum. You can't leave your mind empty because, if you do, some evil influence or pressure will come in. You have got to fill it with the peace of God and the peace of God will guard your mind. The Greek word means 'garrison your mind'; hold your mind so that no evil pressures or tormenting influences can find access to your mind.
Dear Father, thank You for the precious peace of mind that You give me, and for Your Holy Spirit. Please help me to guard my mind, to focus my mind upon You, and to fill my mind with good, uplifting, positive things, especially Your Word, so that I may continue to have this peace. In Jesus’ Name, Amen.
