As long we all remain humans in this world, we all wrestles with sins every single day of his or her life.
There is nowhere does the Bible say that a Christian in this life will ever be perfect.
Even the Christians try all there possible best to a sin free life to be free from all sins.
But as long we are all here on this earth, we will always struggle against temptation and sin.
That is one very important reason why Jesus taught his disciples to pray (in The Lord’s Prayer), “Forgive us our sins … And lead us not into temptation, but deliver us from the evil one” (Luke 11:4, Matthew 6:13).
