Hi Youth,
Jesus began His ministry with the message 'Repent for the Kingdom of Heaven is at hand'.
We can be certain that Jesus wants us to turn away from sin, however we all need the power of the Holy Spirit to help us.
Read Romans about the struggle that Paul had with his carnal desires and came to the conclusion that it is only with Christ's help can we grow more like Jesus. If we live after the flesh we will die but if we live after the Spirit we will live. I pray that you will seek to be filled with the Spirit and seek to walk after the Spirit.
God bless
