The answer to this question is determined by our decision to follow Christ or follow the desires of our flesh.
Whether we believe Him or not, God is God, but He will only be our Lord, Master, in this life if we allow Him to direct our steps.
I know, O Lord, that the way of man is not in himself, that it is not in man who walks to direct his steps (Jer 10:23 ESV).
Trust in the LORD with all of your heart, and lean not on your own understanding, in all your ways acknowledge Him and He will direct your steps, make straight your paths (Prov 3:5–6).
Stop trusting in man, who has but a breath in his nostrils. Of what account is he? – Isa 2:22
It is literally fruitless for man to trust in himself or mankind! This kind of life is comparable to a bush struggling to bear fruit in a wasteland, a salt flat, where no one lives. Fruitfulness comes from trusting in God and putting our confidence in Him. This will bring us a fruitfulness far beyond our circumstances (Jer 17:5–8).
For us today, this means we must live under the power and direction of God’s Holy Spirit:
Those who live according to the sinful nature have their minds set on what that nature desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires. 6 The mind of sinful man is death, but the mind controlled by the Spirit is life and peace; 7 the sinful mind is hostile to God. It does not submit to God’s law, nor can it do so. 8 Those controlled by the sinful nature cannot please God. 9 You, however, are controlled not by the sinful nature but by the Spirit, if the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, he does not belong to Christ. 10 But if Christ is in you, your body is dead because of sin, yet your spirit is alive because of righteousness. 11 And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies through his Spirit, who lives in you (Rom 8:5–11 NIV).
