Often we think of sharing in terms of giving
something that we have to another.
However, we can share in other ways!

A burden shared is only half a burden.
A joy shared is double joy.

Note the following Bible references:

Shared Joy
But even if I am being poured out as a drink offering upon the sacrifice and service of your faith, I rejoice and share my joy with you all. And you too, I urge you, rejoice in the same way
and share your joy with me.
Philippians 2:17-18

Shared Burdens
Bear one another's burdens, and thus fulfill the law of Christ.
Galatians 6:2

Shared Emotions
Rejoice with those who rejoice, and weep with those who weep.
Romans 12:15

Shared Sufferings
And if one member suffers, all the members suffer with it;
if one member is honored, all the members
rejoice with it. Now you are Christ's body,
and individually members of it.
1 Corinthians 12:26-27
