“ Satan wants us to focus on the problem, not the Provider. He constantly points to what seems to be rather than to what God has promised to do. If we stop spending time with the Lord in prayer, the concerns of the physical world snatch our attention and dominate us, while the spiritual senses deaden and the promises fade.I am absolutely convinced that the number one reason that Christians today don't pray more is because we do not grasp the connection between prayer and the promises of God. We are trying as individuals and churches to pray 'because we're supposed to' without a living faith in the promises of God concerning prayer. No faith life of any significance can be maintained by this 'ought-to' approach. There must be faith in God at the bottom....When real faith in God arises, a certainty comes that when we call, he will answer...that when we ask, we will receive...that when we knock, the door will be opened... ”
