God's commands are designed to guide you to life's very best. You will not obey Him, if you do not believe Him and trust Him. You cannot believe Him if you do not love Him. You cannot love Him unless you know Him.
Trust is faith that has become absolute, approved, and accomplished. When all is said and done, there is a sort of risk in faith and its exercise. But trust is firm belief; it is faith in full bloom. Trust is a conscious act, a fact of which we are aware.
Trust perfected is prayer perfected. Trust looks to receive the thing asked for and gets it. Trust is not a belief that God can bless or that He will bless, but that He does bless, here and now. Trust always operates in the present tense. Hope looks toward the future. Trust looks to the present. Hope expects. Trust possesses. Trust receives what prayer acquires. So, what prayer needs, at all times, is abiding and abundant trust.
Assurance grows by repeated conflict, by our repeated experimental proof of the Lord's power and goodness to save; when we have been brought very low and helped, sorely wounded and healed, cast down and raised again, have given up all hope, and been suddenly snatched from danger, and placed in safety; and when these things have been repeated to us and in us a thousand times over, we begin to learn to trust simply to the word and power of God, beyond and against appearances: and this trust, when habitual and strong, bears the name of assurance; for even assurance has degrees.
