I know, I know, I quote from Alistair Begg a lot. But who can help this, he loves the Lord with a poet's heart, and is especially eloquent when he speaks of His grace!
For of His fullness we have all received, and grace upon grace.
You then, my child, be strengthened by the grace that is in Christ Jesus
2 Timothy 2:1
"...the sap of grace flows from the stem to the branch, and when it is perceived that the stem itself is sustained by the very nourishment that feeds the branch. As we day by day receive grace from Jesus, and more constantly recognize it as coming from Him, we shall behold Him in communion with us and enjoy the joy of communion with Him. Let us make daily use of our riches and constantly come to Him as our own covenant Lord, taking from Him the supply of all we need with as much boldness as men take money from their own wallet."
