If you plant an apple tree in your back yard, you can expect to one day see pears on the branches, right? Of course not!
If you put tomato seeds in the ground, one day you can expect to see potatoes growing, right? Of course not!
What you put in the ground is what comes out of the ground. What you sow, you reap (Galatians 6:7). Jesus describes it this way: “For every tree is known by its fruit” (Luke 6:43). What hangs on the limbs of the tree identifies what type of root exists under the tree.
If someone claims to be a Christian, then it follows that there should be “Christian” fruit coming from his life. A believer’s walk should validate his talk. How he lives should authenticate his words.
Thankfully, a faithful God stands behind this truth. He promises to complete what He has begun in His child (Philippians 1:6). He grows what He has “planted” in His people. The seed of faith He sowed in the heart (Ephesians 2:8) will spring forth into belief unto eternal life.
And yet, while He does His work, something remains. Every follower of Christ has the privilege to exercise this contribution to the equation: obedience. He has planned our steps; we must take them. He gives faith; we must walk by faith.
