Self-control

But the Holy Spirit produces this kind of fruit in our lives: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. There is no law against these things! (Galatians 5:22 NLT)

Self-control has to be a fruit of the Spirit. It is pretty impossible to generate it ourselves - maybe we can for a day, a week or even a month, but can we sustain it? Without the Spirit of love in our heart it is very hard to. 

As we live in love we discover that self-control is not an act of the will, or a conscious decision, but it is a heart response. It's the desire to see love triumph, to be silent when we would otherwise judge or condemn, to raise another up rather than push them down.

​In our strength it's impossible, but as we live by the Spirit we find we are 'given desires that are the opposite of what the sinful nature desires' (Galatians 5:17 NLT)
