Jesus means that in us we will be living in God's own peace which keeps our hearts and our minds so we do not suffer in confusion and anxiety and nasty angry reacting and arguing and complaining and unforgiveness and other anti-love things. We have rest in us, because God's grace is almighty to keep Satanic things from messing with us. And we have the personal guiding of God's peace ruling in us >
"And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful." (Colossians 3:15)
God satisfies and guides us, in this peace. And this makes us "content with such things as you have" (Hebrews 13:5), so we do not give in to Satan's dominating and dictatorial drives for pleasures; enough is enough > Philippians 4:11-13.
And "Love suffers long and is kind," our Apostle Paul says in 1 Corinthians 13:4. God's love in us is kind to our souls while making us also kind to others, so we can be pleasantly patient inside ourselves, spiritually and emotionally.
2 Corinthians 12:7-11 < because of how God's grace almighty took care of Paul inside himself, Paul took "pleasure" in his troubles which were for Jesus.
But we can get our own selves into things which are hard for us, if we do not keep on being prayerful and submitting to how our Heavenly Father personally guides us in His own peace. Therefore, if negative and nasty and naughty stuff gets started in us, we need to stop right away and seek God to correct and restore us into sweet and pleasant and sensitive intimacy with Him and submit to how He rules us in His peace, and discover what He really has us doing with Him
One problem is we can make sacrifices which God is not leading us to do. And then we can get tied up in things and things can get us under their power (1 Corinthians 6:12). And then can come stress and worry and hurry and getting hurt and wasted and burnt out. So, keep learning how to walk with Jesus in His love's "rest for your souls." (Matthew 11:28-30)
And enjoy loving. Do not suppose that we can have rest by staying away from our Jesus family people. Yes, other children of God can be wrong, somehow, and we can get hurt, even, and get in scuffs. But our Father has us so we need one another, to minister God's own word and His grace to each other > 1 Peter 4:17 < so we can not have true peace and rest by isolating ourselves and judging other Christians as an excuse to stay away from one another, but >
"with all lowliness and gentleness, with longsuffering, bearing with one another in love," (Ephesians 4:2)
We need to have "longsuffering" ready, then, all the time, even with ones who really are Christians and who are mature. Because any of us can be wrong, at times; and our Father knows this; so He commands us all to be ready with "longsuffering", so we are ready to help to restore one another (Galatians 6:1, James 5:16) > Jesus never gave up on any of His disciples. So, while we are ready to be longsuffering and to forgive each other, we are strong in His rest so we can not be taken down and out about how any of us can at times be wrong.
In case another Christian or a church leader is wrong, we can have rest by depending on God to do what is right. With God, we always can do the thing which is right, which God has us doing > because of his obedience, Abraham has gotten "all the nations of the earth" "blessed" > see Genesis chapter 22. God uses prayer, correction, and example > 1 Peter 5:3.
"Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice. And be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you." (Ephesians 4:31-32)
This comes with actively seeking our Father for His correction > Hebrews 12:4-11 > while growing in Jesus who shares His own pleasant rest with us.
