"And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge; And to knowledge temperance; and to temperance patience; and to patience godliness; And to godliness brotherly kindness; and to brotherly kindness charity."(2 Peter 1:5)
There is nothing you have that cannot be added to. This is the mindset of continual improvement and progress. What you don't improve upon will reduce with time. It is through improvement that we maintain balance and standard. For whatever is not updated becomes outdated. The technological world of 'constant updates' makes us aware of how out of sync it is to use software or programs that are not updated. Our spiritual lives too must have constant spiritual updates!
Updating or improving every area of our lives is first a mindset. Then secondly, it's a daily work of adding small things here and there. This is what Peter referred to here, to your faith add diligence and to diligence add kindness. In other words, you can always add to what you have! It is in the process of daily additions that we make constant improvement.
Isaiah shared a similar thought in Isaiah 28:10,
"For precept must be upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little". Improvement is not a quantum leap, it is a daily walk of adding one thing, one skills, one thoughts, one adjustment, to your life that wasn't there before.
Improvement is made by daily pressing into new things. Paul said he forgets those things that are behind and press into new territories.
‘Brethren, I do not count myself to have apprehended; but one thing I do, forgetting those things which are behind and reaching forward to those things which are ahead, I press toward the goal for the prize of the upward call of God in Christ Jesus.’
The new living translation says it this way, ‘I don’t mean to say that I have already achieved these things or that I have already reached perfection. But I press on to possess that perfection for which Christ Jesus first possessed me. No, dear brothers and sisters, I have not achieved it, [a] but I focus on this one thing: Forgetting the past and looking forward to what lies ahead, I press on to reach the end of the race and receive the heavenly prize for which God, through Christ Jesus, is calling us. Let all who are spiritually mature agree on these things. If you disagree on some point, I believe God will make it plain to you’
When we press we possess when we slack we are left behind! This must be our determination then, to daily press into new heights in God and in every area of our lives.
