Its pretty obvious that this man has a problem that is bothering him a lot! While we all have struggles, his seems to be severe. Christians are forgiven from their sins, but we still have problems. Sin, Satan and the pressures of this world to just "go along" with what everyone else is doing can cause angst for even the most dedicated of disciples.
These things are nothing new, but they are worth remembering. The apostle Peter puts it this way...
1 Peter, Chapter 2 (WEB)
1 Putting away therefore all wickedness, all deceit, hypocrisies, envies, and all evil speaking, 2 as newborn babies, long for the pure milk of the Word, that with it you may grow, 3 if indeed you have tasted that the Lord is gracious: 4 coming to him, a living stone, rejected indeed by men, but chosen by God, precious. 5 You also, as living stones, are built up as a spiritual house, to be a holy priesthood, to offer up spiritual sacrifices, acceptable to God through Jesus Christ. 6 Because it is contained in Scripture,
“Behold, I lay in Zion a chief cornerstone, chosen, and precious:
He who believes in him will not be disappointed.”
7 For you who believe therefore is the honor, but for those who are disobedient,
“The stone which the builders rejected,
has become the chief cornerstone,”
“a stone of stumbling, and a rock of offense.”
For they stumble at the word, being disobedient, to which also they were appointed. 9 But you are a chosen race, a royal priesthood, a holy nation, a people for God’s own possession, that you may proclaim the excellence of him who called you out of darkness into his marvelous light: 10 who in time past were no people, but now are God’s people, who had not obtained mercy, but now have obtained mercy. 11 Beloved, I beg you as foreigners and pilgrims, to abstain from fleshly lusts, which war against the soul; 12 having good behavior among the nations, so in that of which they speak against you as evildoers, they may by your good works, which they see, glorify God in the day of visitation.
When in times of trouble, when the world seems too much for you, remember what Jesus did for you and do the right things. Concentrate on the good- be everything God wants you to be. Yes, there will still be problems, but we can overcome anything the world can throw at us.
Ultimately, we have the victory! Rejoice!!
