Do

How?
Thankfully in the name of Jesus,
And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him. (Colossians 3:17 ESV)
In love,
Do everything in love. (1 Corinthians 16:14 NIV)
As unto the Lord,
Whatever you do, work at it with all your heart, as working for the Lord, not for human masters, (Colossians 3:23 NIV)
To His glory.
So, whether you eat or drink, or whatever you do, do all to the glory of God. (1 Corinthians 10:31 ESV)

Why?
We love, because He first love us.
We love because he first loved us. (1 John 4:19 ESV)
We forgive, because we were forgiven.
Be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you. (Ephesians 4:32 ESV)
Put on then, as God's chosen ones, holy and beloved, compassionate hearts, kindness, humility, meekness, and patience, bearing with one another and, if one has a complaint against another, forgiving each other; as the Lord has forgiven you, so you also must forgive. (Colossians 3:12-13 ESV)
We give, because we were given.
Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give. (Matthew 10:8 KJV)
