It’s not easy. You will need to ask God for help to be faithful. Perhaps, this is a quick reminder that, we are dependent on our heavenly Father for everything. There is no need to boast about anything. The Psalmist long ago identified our dependency on God. Please keep praying in order to be faithful.
Create in me a clean heart, O God; and renew a right spirit within me. Cast me not away from thy presence; and take not thy holy spirit from me. Restore unto me the joy of thy salvation; and uphold me with thy free spirit. Psalm 51: 10-12 (KJV)
On account of what are we Christians? Everyone would say, “On account of faith”.
– St. Basil the Great
