In this message Paul spells out that suffering is part and parcel of the Christian life. Successful life always produces demands, therefore Christians are to think carefully about the challenges of life knowing that God uses all for our good and His glory.
2 Timothy 2:3-7 English Standard Version (ESV)
3 Share in suffering as a good soldier of Christ Jesus. 4 No soldier gets entangled in civilian pursuits, since his aim is to please the one who enlisted him. 5 An athlete is not crowned unless he competes according to the rules. 6 It is the hard-working farmer who ought to have the first share of the crops. 7 Think over what I say, for the Lord will give you understanding in everything.
