Psalm 111:2: The works of the Lord are great, sought out by all who delight in them.
What do you do when you find out something special and rewarding? Do you share it with others or keep it to yourself instead?
When we find out the truth which is in the Gospel, we want to share it with others so they can get to know this special relationship with Christ. We also find great joy in hearing the truth and how it attains to us in our lives.
God wants us to know and wants us to share in that joy and truth. The more we find out the more we want to be able to share it with others - this all stems from Christ's commandment to us - to love one another.
Sharing good things with the people you love is rewarding to yourself, to them and a great blessing to God as well.
