Many waver at current circumstances; but wavering only compounds the uncertainty.
Faith is believing despite the physical senses. Oftentimes, the disconnect is experienced because the spiritual senses have not been sharpened through intimacy with the Lord.
Although intimacy with the Lord sounds simple, complication arises when the physical does not equate with our belief and understanding of the spiritual: what we read and hear from the Word of God.
This is often where faith is exercised most strenuously, as we push forward in believing the Word will overcome the circumstances we endure as we reap unpleasant harvests from bad seeds of the past.
Faith is the action of sowing good seed in the midst of reaping bad; understanding that eventually the season of bad seed will end, and the reaping of the good seed will begin.
Faith is again tested as good seed is planted, but seemingly unpleasant circumstances abound. This is the sanctification process where circumstance is used to fulfill maturity, not because of something we did, but because who we are to become.
Knowing we are maturing is the faith which produces the ability to withstand any circumstance, regardless of the outcome.
Spiritual growth is eternal, and faith is the engine that drives it.
James 1:6-7 But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed. For let not that man think that he shall receive any thing of the Lord.
Hebrews 11:6 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.
Hebrews 11:1 Now faith is the substance of things hoped for, the evidence of things not seen.
Mark 12:30 And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.
James 2:18 Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works.
James 2:21-24 Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar? Seest thou how faith wrought with his works, and by works was faith made perfect? And the scripture was fulfilled which saith, Abraham believed God, and it was imputed unto him for righteousness: and he was called the Friend of God. Ye see then how that by works a man is justified, and not by faith only.
James 1:3-4 Knowing this, that the trying of your faith worketh patience. But let patience have her perfect work, that ye may be perfect and entire, wanting nothing.
2Corinthians 4:17 For our light affliction, which is but for a moment, worketh for us a far more exceeding and eternal weight of glory;
Galatians 6:9 And let us not be weary in well doing: for in due season we shall reap, if we faint not.
