Sister, i know what are you going through. Those are fiery darts from the enemy, The enemy will remind you of your past sins to upset you ad to make you doubt your salvation. Sister, if you repented and you asked Jesus for forgiveness your sins are forgiven. Continue to keep away from those things and know that you are loved by Jesus. Trust in Jesus and keep Him close to you. When you feel attacks on you strengthen, start praying and listen to praise music to set your mind on Jesus not on your past sins. God will not keep them against you as He promised.
Keep your eyes on Jesus and rebuke those thoughts in Jesus name.
Glory to Holy Father and praised be our lord and saviour Jesus Christ.
God bless you sister in Jesus mighty name. Amen.
