"For everyone who asks receives; the one who seeks finds; and to the one who knocks, the door will be opened". Matthew 7:8.
The tremendous resource of prayer is far too often neglected by far too many Christians. If nothing is standing between us and the Lord to keep us from asking effectively (sin, unbelief, selfish motives, etc.), then God has promised to act when we ask by giving us our request or something better. Note just a few of the many promises to those who ask:
"If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you". James 1:5.
"Until now you have not asked for anything in my name. Ask and you will receive, and your joy will be complete". John 16:24.
"This is the confidence we have in approaching God: that if we ask anything according to his will, he hears us. And if we know that he hears us—whatever we ask—we know that we have what we asked of him". 1 John 5:14-15.
"You may ask me for anything in my name, and I will do it.". John 14:14.
"And receive from him anything we ask, because we keep his commands and do what pleases him". 1 John 3:22.
"If you then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give the Holy Spirit to those who ask him!”. Luke 11:13.
"If you remain in me and my words remain in you, ask whatever you wish, and it will be done for you". John 15:7.
Obviously, there are conditions. These marvelous promises assume that those who ask are abiding in His commandments, truly desiring His will, having His priorities, thinking His thoughts, and are asking in faith and in His name.
