Every human being is dependent on someone or something. When people are sick they depend on doctors and medications to help them. When we are hungry and thirsty we depend on food and water to satisfy them. If we want to travel to another country we depend on transportations to take us there. But behind all of these is an ultimate source. God is the source of everything we have and will ever have.
The Apostle Paul tells us that Christ is the one who enables us to do all things. Christ is both the source and the means in everything in life that we need. He is the creator and the sustainer of all things. And He is the same yesterday, today and forever; so He changes not. How can we access what we need from Him? The bible says, it is through faith in God. The ones who have faith in God are discribed as the righteous.
If we are going to make it in life in any area we must focus on Christ at all times. Like Peter, walking on the water, the moment we fail to trust in Jesus we begin to sink under the problems of life. But the moment we call on Jesus He rescues us. Let us believe and say like the Apostle Paul, "I can do all things through Christ that strengthens me." Philippians 4:13 (KJV).
