Let us work for the Lord.
It is normal that sometimes we lose focus in some situations in life, our humanity is often much stronger and we do not do the good we want.
God exhorts us to remain firm and constant. Firm and constant in what? In faith, this faith is externalized through works of faith. God wants us to remain in constant spiritual growth. Faith fills us with hope and makes us understand that everything we do is NOT in vain, we will have the reward of good works, the works of FAITH.
Therefore, my beloved brothers, be firm, immovable, always abounding in the work of the Lord, knowing that your labor is not in vain in the Lord.
1 Corinthians 15:58
