2 Timothy 1:7 (NASB)
For God has not given us a spirit of timidity, but of power and love and discipline.
Paul tells Timothy that God has not given them the spirit of timidity (or fear in the ESV). In other words, God has not given Paul and Timothy a tentative heart when it comes to serving God and his people. The same can be said of all believers since each believer has the same Spirit (Eph. 4:4). Although, it is especially the case of those men called to the ministry (preaching, evangelizing, etc.).
So, what has God given Paul, Timothy, ministers, and all believers? The NASB translates the word πνεῦμα (pneuma), spirit, in the sense of God’s controlling influence, whereas some translations actually translate this word as Spirit (as in the Holy Spirit). Whether it is the spirit or Spirit that is meant by Paul the result does not much matter since all believers, in this specific case Paul and Timothy, are given the same spirit and Spirit. Either way, it is God who has the controlling influence and power in the life of the believer to overcome timidity (fear).
It is God who enables the believer to serve him and because of this, every believer can overcome fear. Not only can a believer overcome fear, but they can overcome weakness. For God’s strength is made perfect in weakness (2 Cor. 12:9) and his Spirit or the spirit he has given the believer is one of power.
The spirit God has given the believer is also that of love. His power enables the believer to overcome themselves and pursue the needs of others. This type of power to overcome a tentative spirit removes any form of selfishness in a Christian. If a person is selfish, they only think of what they will get out of serving God or be afraid of losing their prestige, power, or money. The love God enables the believer to have is one of sacrifice for others and one of courage.
Lastly, God gives the Christian the gift of discipline. Essentially, the one with this God-given spirit is sensibly minded and can control themself. The believer lacks nothing. Everything they need to serve God they have been given!
If you are a Christian you have every reason not to be tentative in spirit! God has given you all you need to serve him. God’s gifting of his Spirit enables you to be strong and very courageous in order to work for his purposes.
