Grace and peace to you from God our Father.
We often think about Jesus [He is Worthy] and the Holy Spirit [especially in Pentecostal-type circles], but how often do we think about the Father? I know we do when we say the Lord's Prayer. Other than that, I don't hear much about Father God, yet He is mentioned many times in the New Testament.
Here Paul prays that grace and peace would come from the Father. The Father is the One Who initiated the plan of Salvation by sending the Son. Jesus said that the Father Himself loves us. In 1 Cor. 8:6, Paul tells us that all things come from the Father, and we live for Him. As we praise, worship, give things and meditate on Almighty God, let's not forget about the Father.
And remember that our earthly fathers, no matter how good or bad they were, are not the picture of Who God is; instead, God the Father is the image of who they are supposed to be.
