When building a house, you start with the foundation. The foundation is only the beginning, there are other things you must do to finish the house. Our Christian life is the same. Accepting Jesus as our Savior is just the beginning, Most Christians have the foundation poured and that’s it, period. They get their free gift and that’s the end. They never begin putting up the walls, or roof, and their life in Jesus never becomes a home. I don’t know about you, but my home is my protection. There is a real powerful enemy out there that’s trying to get us, but if we do not start building upon our foundation in Jesus, we will be completely exposed to the enemy. D.L. Moody says it like this in his book THE OVERCOMING LIFE:
It is like this: when a man enters the army, he is a member of the army the moment he enlists; he is just as much a member as a man who has been in the army ten or twenty years. But enlisting is one thing, and participating in a battle another. Young converts are like those just enlisted.
Going to church is not enough, you must do more. You received your free gift, but the rest has to be worked for. I call it work because it’s not easy to crucify your flesh daily to follow Him. You have to lay down your old life and begin building the walls, and putting on the roof of your new home. If you have enough faith to believe that He is your Savior, you have enough faith to build your life in Him.
If the work that anyone has built on the foundation survives, he will receive a reward. If anyone's work is burned up, he will suffer loss, though he himself will be saved, but only as through fire. 1 Corinthians 3:14
