Proverbs 25:28
A man without self-control is like a city broken into and left without walls.
So, according to this translation, there is such a thing as self-control.
But a serial predator can control oneself while there is a police officer nearby.
But what about self-control which is included in the fruit of the Holy Spirit? I would say this would not be the same.
And, yes, humans on our own can fail in self-control, since Jesus says, "without Me you can do nothing" (in John 15:5).
But yes if we control ourselves to put something which can be distracting out of the way, yes this can help, but it does not solve the problem of however our nature makes us available to Satan's spirit "who now works in the sons of disobedience" (in Ephesians 2:2). We need how God changes our nature so we can not be violated and corrupted and weakened to do wrong things. The self-control of the Holy Spirit's love in us is almighty so with God it is possible to easily make temptation stuff of Satan flee.
"Therefore submit to God. Resist the devil and he will flee from you." (James 4:7)
This is possible with God. And we grow in this, I would say, as we grow in Jesus.
Also, we can exercise to get stronger, as we keep saying no to arguing and complaining and other anti-love things > Philippians 2:13-16.
"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)
Yes, in our self-control which is of love, we have ability to forgive "even as God". Because God in us shares this with us, by means of His grace almighty which is so unconditionally loving and so generously forgiving. As we get stronger in such forgiving which is living in God's love, we become also stronger against any evil drives and feelings and deceptive thinking of temptation. So, we trust You, God our Father, for this real correction which only You are able to do in us; thank You; amen . . . . . . . .
