A company of believers is weak due to poor leadership. Paul writes here in 2 Timothy 2 addressing this issue with the hope to inspire his spiritual son. Timothy battled with timidity; that is why Paul said more than once for him to be strong through the grace given him. Joshua also battled timidity, as seen in Joshua chapter 1, where the Lord told Joshua three times to be strong and courageous. I, for one, struggled with this, but with growing in my relationship with the Lord over time and seeing His hand at work in my life, I am now quite bold and confident. We cannot receive this strength by lifting weights; it's by grace that increases the closer we get to God.
Each individual in the body of Christ has been given a portion of faith; combined with other believers, it grows. So we can only go so far on our own; we need each other. This is why Paul told Timothy in verse two to find other trustworthy people that can take what he has taught and teach others. We are only as strong as our team, so only little will be accomplished if my team is me, myself, and I. Leaders lead leaders who lead leaders! Kingdom advancement is based on bearing fruit and multiplying.
Spiritual strength is characterized by endurance, as seen in verses 3-4, with the examples of good soldiers and athletes. To be good means to be dedicated where you know the rules, practice regularly, and are not easily distracted by trivial pursuits. If you put in the time, you will see the results, just as the example of farmers in verse six reaps a harvest because of their hard work. Another characterization of strength, as seen in verses 9-13, is long-suffering. The definition being having patience despite having troubles. Jesus promised that those that follow Him would suffer, for the lovers of darkness hate those in the light. The gospel brings light, so whosoever preaches it will be persecuted by those who love the dark. Strong leaders face suffering from joy knowing they are participating in carrying the cross of Christ.
Spiritually strong leaders work hard! They have a vision, and so, therefore, every step they make is driven with purpose. They avoid fruitless activities and conversations. Time is of the utmost importance, so anyone or anything that would rob them of this is avoided. They study the gospel daily, so they need not be ashamed when they preach, for they have rightly divided the Word of Truth.
Spiritually strong leaders stay away from evil things; they run from anything that would compromise their faith. As it says in verses 19-22, they desire to be special utensils of gold and silver, not wood and clay, so they keep themselves pure so they can be honorable vessels that the Master can use for special occasions. (2 Timothy 2:19-22)
Spiritually strong believers are servant leaders who do not quarrel but are kind to everyone, teach well and are patient with difficult people. They have the grace to help other believers avoid the devil's traps or come out of them.
The charge is for us to repent for any area we fall short as leaders and draw ever closer to the Lord to gain more strength to serve others in a more godly manner.
