Let’s look at Psalm 127:3 in different translations.
Sons are a heritage from the Lord, children a reward from him. (NIV)
Behold, children are a gift of the LORD, The fruit of the womb is a reward. (NASB)
Children are a gift from the Lord; they are a reward from him. (NLT)
Usually, people are thankful for a gift that is given to them and treat it as such. If we hold our children as gifts from God, then we raise them up in loving care. A gift is given to someone in love and accepted with thanksgiving. A reward is earned or given in recognition. If we, as mothers, consider our children gifts and ourselves rewarded with their very presence, how different would some of our days look! As for the ministry of motherhood, we train up our children in the nurture and admonition of the Lord because we love them and want them to know the Lord. What greater thanks can we show for the gift of children than to return them to His service as young adults!
