satan sometimes seems to cloud my vision from the truth
Dear brother,
We must never underestimate our enemy. For once we become unaware, let alone willingly ignorant, of his wiles, we'll surely fall into his snares. HOWEVER, we also must never trust our feelings, mood, what others say, etc., more than we trust the Lord. We must not focus on our inability or our natural condition. "For [i]we walk by faith[/i], not by sight"--the Apostle writes. If we look UNTO THE LORD, and lose ourselves in Him, He will NEVER fail us, nor desert us. He, our God and our only Hope, "is ABLE to keep you from stumbling, And to present you faultless Before the presence of His glory with exceeding joy" (Jude 1:24); "it is God who works in you both to will and to do for His good pleasure" (Phil. 2:13). Don't doubt that! Rest on His eternal promises, brother. Your Heavenly Father is able to deliver us out of every temptation; even when we don't feel like being delivered, He provides a way out by grace.
Brother, let your mind and hope be fixed upon Him! The Word says, "You will keep him [i]in perfect peace[/i], Whose mind is stayed on You, Because he trusts in You" (Is. 26:4). Look for HIS STRENGTH. God is your Rock and your Shield. Don't look back. Don't look at yourself or your past failure. Remember, you can't (and don't try to) improve your flesh (that's why it's been judged and crucified in Christ); the power to "do all things" and "to be more than a conqueror" is all in and from and through Him. And He's done it all! He's overcome the world, so be of good cheer (Jn. 16:33). The war has been won once and for all. Enter into His rest, brother, and never look back! Do you have a mustard seed of faith?
And you know, you may fail... you may try too hard to "trust" Him more, and to "depend on" Him more, and to be "more watchful," and "more obedient"... but during this process of wrestling with yourself, brother, only God by His infinite mercy, may visit you, and show you your absolute insufficiency, and your total hopelessness, and reveal to you the truth and absolute necessity of His grace. There is something of this in His word, "And I give them eternal life, and they shall never perish; [i]neither shall anyone snatch them out of My hand[/i]" (Jn.10:28). And then you will know that HE--not you or any man--but God alone has delivered you out of your predicament. You'll know that you can never save yourself, or ever live unless you are kept by the power of God.
