I don't claim to be a general contractor, but I do know that a good foundation is paramount for the longevity of any structure.
What is the foundation of your relationship with God?
In America, there is a large group of people who would admit they believe God exists. But believing God exists is far different than believing in God.
Believing in God is another story.
Abraham believed the promise of God that his descendants would be more numerous than the stars. He believed God existed, and then he believed in God.
When God revealed himself to Moses in the burning bush, Moses did not simply believe that God was real, he believed that God was going to deliver the Israelite people out of bondage. He believed this because he believed in God.
Jesus cried out from the cross, “Father forgive them...," He didn't just believe God the Father existed. He was able to extend forgiveness because he believed in God, even in the face of death.
Believing God exists doesn't take much effort, but to believe God is at work in our lives, to believe His Word is true, to believe He has given us the Holy Spirit to empower us requires us to live radically different lives. Lives that are built on a firm foundation, solid and unmoveable.
In Genesis 15:6, this foundation of believing in God was laid for all of us.
Abram believed the Lord, and he credited it to him as righteousness.
In the New Testament, Ephesians 2:8-9 says,
For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God—not by works, so that no one can boast.
The foundation that we build on is believing in God, just like Abraham, Moses and even Jesus did, I believe.
