Christ said to Martha at the grave of Lazarus, “If thou wouldest believe, thou shouldest see the glory of God.” John 11:40.
But many have not a living faith. This is why they do not see more of the power of God. Their weakness is the result of their unbelief. They have more faith in their own working than in the working of God for them. They take themselves into their own keeping. They plan and devise, but pray little, and have little real trust in God. They think they have faith, but it is only the impulse of the moment. Failing to realize their own need, or God's willingness to give, they do not persevere in keeping their requests before the Lord.
Our prayers are to be as earnest and persistent as was the petition of the needy friend who asked for the loaves at midnight. The more earnestly and steadfastly we ask, the closer will be our spiritual union with Christ. We shall receive increased blessings because we have increased faith.
Our part is to pray and believe. Watch unto prayer. Watch, and co-operate with the prayer-hearing God. Bear in mind that “we are labourers together with God.” 1 Corinthians 3:9. Speak and act in harmony with your prayers. It will make an infinite difference with you whether trial shall prove your faith to be genuine, or show that your prayers are only a form. COL 145,146
