In Proverbs, we learn that a generous person will prosper (Proverbs 11:25). In Galatians, Paul writes the famous words: "For whatsoever a man soweth, that shall he also reap." (Galatians 6:7) In these closing words to the Corinthian church, Paul again discusses about the wisdom of generosity - Being generous with our gifts and giving isn't a legal requirement for meeting the demands of the church or denomination, but simply because cheerful giving and wise generosity delight the Lord Who has saved us by His grace and has given us everything we need.
Our God is all-powerful. Because He created all things, He can supply all our needs. However, don't skip the second part - The Lord gives us blessings so that we can live a life full of good works! Our lives will be full of good deeds if we generously share in the name of Jesus, as the apostle Paul encourages. When we take our eyes off of our possessions and focus less on what we lack, we begin to see that God has all we need to live purposeful lives.
So don't be afraid to give generously to people in need. Whenever you need anything, God will provide it! His grace abounds toward you, and He is able to provide all you need.

Dear Heavenly Father, thank You for the free gift of salvation and for the many blessings You have lavished upon me by grace. Although I know You can provide for all my needs, I often doubt whether You will. Please teach me how to trust You in times of need and follow You more closely in faith. Give me a generous heart that gives cheerfully and willingly to others, regardless of my circumstances. When I don't have the resources to help others, help me to show compassion and kindness to those in need and to pray for them. We can trust You to provide for all our needs!
In Jesus's name I pray. Amen.
