The best and most efficient type of prayer, is the prayer that comes from a sincere and pure heart.
God knows exactly what’s in your heart, so it will be wrong to come to God in prayer, without exposing you true desires and intentions to Him.
Do not let anything come in between you and God, when you are praying: neither your sin, your pride or your lack of faith.
Kindly remember, that God is both your Father and Almighty meaning when you come to Hm in prayer, do not overthink things too much, just pour out your heart to Him, and let His sovereign will do the rest. Because He will do all things according to His will.
God cares about every aspect of your life, so do not leave out the simple things from Him: like your health, food, friendships, studies and even relationships.
And believe me, you will start seeing a lot more of your prayers being answered according to His will.
God bless you and have a wonderful day.
