While living a Christian life, one should remember that LORD not only bless us but through us he wants to bless others. If we see the nature closly, it reveals that Nature is following the principal of blessing others. Sun is continully giving his light, heat and features to every living thing on our earth and demands nothing in return. Tree gives its fruit , wood, oxygen,shadow to human, birds, animals etc. but don't eat its fruit itself. While living a life of believer we must be a helpful individual. We should possess an attitude of giving our best to those who deserve our better. The life of Christ is a great example . He preached, healed, fed, taught, evanglized , and did his best through his life to help the humanity and before his ascention, asked his disciple to continue his mission. Therefore, We the christians have to keep the spirit of Christ and through our life we have to bless others. Whatever God has given us is our blessing which is sufficient for us and sufficient to share with others as well.
In genesis 12:3 , LORD promised to bless Abraham and through him nations.......means LORD expect that through Abraham and his children , he would bless nations and he did that.
We can pray , O lord bless me and let me be a blessing for others........ and he will bless us abundently.
God bless you
