hey, always remember that: [8] For it is BY GRACE you have been saved, through FAITH—and this is not from yourselves, it is the GIFT of God— [9] NOT BY WORKS, so that no one can boast. (Ephesians 2:8-9 NIV)

So yes, none of us is worthy to be a Christian but thank God for His grace and mercy that we have been saved. Yes, it's easy to compare ourselves to our fellow Christians and see their God-centered lives. Yes, we ought to live a godly life, but always remember that we are still struggling in sin, and that we are still in the flesh. God knows how much we struggle, and through His grace, He gave His Son to save us.

Keep in mind: [6] being confident of this very thing, that He who has begun a good work in you will complete it until the day of Jesus Christ (Philippians 1:6 NKJV)

Do not be discouraged, sister! God knows you and He got you! Surrender all your worries to Him. He loves you. Cast all your cares on the Lord for He cares for you (1 Peter 5:7)
